Designed with the modern Linux system in mind, it offers a robust framework for different forms of application communication. +D-Bus is 'n gesofistikeerde **inter-Process Communication (IPC) stelsel** wat toepassings in staat stel om doeltreffend te kommunikeer en data te deel. Dit is ontwerp met die moderne Linux-stelsel in gedagte en bied 'n robuuste raamwerk vir verskillende vorme van toepassingskommunikasie. -The system is versatile, supporting basic IPC that enhances data exchange between processes, reminiscent of **enhanced UNIX domain sockets**. Moreover, it aids in broadcasting events or signals, fostering seamless integration among system components. For instance, a signal from a Bluetooth daemon about an incoming call can prompt a music player to mute, enhancing user experience. Additionally, D-Bus supports a remote object system, simplifying service requests and method invocations between applications, streamlining processes that were traditionally complex. +Die stelsel is veelsydig en ondersteun basiese IPC wat data-uitruil tussen prosesse verbeter, wat herinner aan **verbeterde UNIX-domein sokette**. Boonop help dit om gebeurtenisse of seine te versprei, wat naatlose integrasie tussen stelseldelers bevorder. Byvoorbeeld, 'n sein van 'n Bluetooth-daemon oor 'n inkomende oproep kan 'n musiekspeler aanmoedig om te demp, wat die gebruikerservaring verbeter. Daarbenewens ondersteun D-Bus 'n afstandsobjekstelsel, wat diensversoeke en metode-aanroep tussen toepassings vereenvoudig, wat prosesse wat tradisioneel kompleks was, stroomlyn. -D-Bus operates on an **allow/deny model**, managing message permissions (method calls, signal emissions, etc.) based on the cumulative effect of matching policy rules. These policies specify interactions with the bus, potentially allowing for privilege escalation through the exploitation of these permissions. +D-Bus werk op 'n **toelaat/ontken model**, wat boodskaptoestemmings (metode-aanroepe, seinuitstralings, ens.) bestuur op grond van die kumulatiewe effek van ooreenstemmende beleidsreëls. Hierdie beleide spesifiseer interaksies met die bus, wat moontlik voorregverhoging deur die uitbuiting van hierdie toestemmings toelaat. -An example of such a policy in `/etc/dbus-1/system.d/wpa_supplicant.conf` is provided, detailing permissions for the root user to own, send to, and receive messages from `fi.w1.wpa_supplicant1`. - -Policies without a specified user or group apply universally, while "default" context policies apply to all not covered by other specific policies. +'n Voorbeeld van so 'n beleid in `/etc/dbus-1/system.d/wpa_supplicant.conf` word verskaf, wat toestemmings vir die wortelgebruiker om te besit, te stuur na, en boodskappe van `fi.w1.wpa_supplicant1` te ontvang, uiteensit. +Beleide sonder 'n gespesifiseerde gebruiker of groep geld universeel, terwyl "default" kontekstbeleide op almal van toepassing is wat nie deur ander spesifieke beleide gedek word nie. ```xml - - - - + + + + ``` - -**Learn how to enumerate and exploit a D-Bus communication here:** +**Leer hoe om 'n D-Bus kommunikasie te evalueer en te benut hier:** {{#ref}} d-bus-enumeration-and-command-injection-privilege-escalation.md {{#endref}} -## **Network** +## **Netwerk** -It's always interesting to enumerate the network and figure out the position of the machine. - -### Generic enumeration +Dit is altyd interessant om die netwerk te evalueer en die posisie van die masjien te bepaal. +### Generiese evaluering ```bash #Hostname, hosts and DNS cat /etc/hostname /etc/hosts /etc/resolv.conf @@ -707,30 +612,24 @@ cat /etc/networks #Files used by network services lsof -i ``` +### Ope poorte -### Open ports - -Always check network services running on the machine that you weren't able to interact with before accessing it: - +Kontroleer altyd netwerkdienste wat op die masjien loop waarmee jy nie kon interaksie hê nie voordat jy dit toegang verkry: ```bash (netstat -punta || ss --ntpu) (netstat -punta || ss --ntpu) | grep "127.0" ``` - ### Sniffing -Check if you can sniff traffic.

For remote access, it's essential to employ HTTPS and **TLS** to ensure confidentiality, integrity, and authentication. - -The Docker engine, by default, listens on the Unix socket at `unix:///var/run/docker.sock`. On Ubuntu systems, Docker's startup options are defined in `/etc/default/docker`. To enable remote access to the Docker API and client, expose the Docker daemon over an HTTP socket by adding the following settings: +Die Docker engine kan plaaslik via 'n Unix-sok of afstandelik met HTTP benader word. Vir afstandelike toegang is dit noodsaaklik om HTTPS en **TLS** te gebruik om vertroulikheid, integriteit en outentisering te verseker. +Die Docker engine luister standaard op die Unix-sok by `unix:///var/run/docker.sock`. Op Ubuntu-stelsels word Docker se opstartopsies gedefinieer in `/etc/default/docker`. Om afstandelike toegang tot die Docker API en kliënt te aktiveer, stel die Docker daemon bloot deur die volgende instellings by te voeg: ```bash DOCKER_OPTS="-D -H unix:///var/run/docker.sock -H tcp://192.168.56.101:2376" sudo service docker restart ``` +egter, om die Docker daemon oor HTTP bloot te stel, word nie aanbeveel nie weens sekuriteitskwessies. Dit is raadsaam om verbindings te beveilig met behulp van HTTPS. Daar is twee hoofbenaderings om die verbinding te beveilig: -However, exposing the Docker daemon over HTTP is not recommended due to security concerns. It's advisable to secure connections using HTTPS. There are two main approaches to securing the connection: +1. Die kliënt verifieer die bediener se identiteit. +2. Beide die kliënt en bediener verifieer mekaar se identiteit. -1. The client verifies the server's identity. -2. Both the client and server mutually authenticate each other's identity. +Sertifikate word gebruik om 'n bediener se identiteit te bevestig. Vir gedetailleerde voorbeelde van beide metodes, verwys na [**hierdie gids**](https://sreeninet.wordpress.com/2016/03/06/docker-security-part-3engine-access/). -Certificates are utilized to confirm a server's identity.

-Summary of Container Security Features +Opsomming van Houer Sekuriteitskenmerke -**Main Process Isolation Features** +**Hoof Proses Isolasie Kenmerke** -In containerized environments, isolating projects and their processes is paramount for security and resource management. Here's a simplified explanation of key concepts: +In gecontaineriseerde omgewings is dit van kardinale belang om projekte en hul prosesse te isoleer vir sekuriteit en hulpbronbestuur. Hier is 'n vereenvoudigde verduideliking van sleutelkonsepte: **Namespaces** -- **Purpose**: Ensure isolation of resources like processes, network, and filesystems. Particularly in Docker, namespaces keep a container's processes separate from the host and other containers. -- **Usage of `unshare`**: The `unshare` command (or the underlying syscall) is utilized to create new namespaces, providing an added layer of isolation. However, while Kubernetes doesn't inherently block this, Docker does. -- **Limitation**: Creating new namespaces doesn't allow a process to revert to the host's default namespaces. To penetrate the host namespaces, one would typically require access to the host's `/proc` directory, using `nsenter` for entry. +- **Doel**: Verseker isolasie van hulpbronne soos prosesse, netwerk, en lêerstelsels. Veral in Docker, hou namespaces 'n houer se prosesse apart van die gasheer en ander houers. +- **Gebruik van `unshare`**: Die `unshare` opdrag (of die onderliggende syscall) word gebruik om nuwe namespaces te skep, wat 'n bykomende laag van isolasie bied. Tog, terwyl Kubernetes dit nie inherent blokkeer nie, doen Docker dit. +- **Beperking**: Die skep van nuwe namespaces laat nie 'n proses toe om na die gasheer se standaard namespaces terug te keer nie. Om in die gasheer namespaces te dring, sou 'n mens tipies toegang tot die gasheer se `/proc` gids benodig, met `nsenter` vir toegang. -**Control Groups (CGroups)** +**Beheer Groepe (CGroups)** -- **Function**: Primarily used for allocating resources among processes. -- **Security Aspect**: CGroups themselves don't offer isolation security, except for the `release_agent` feature, which, if misconfigured, could potentially be exploited for unauthorized access. +- **Funksie**: Primêr gebruik vir die toewysing van hulpbronne onder prosesse. +- **Sekuriteitsaspek**: CGroups self bied nie isolasie sekuriteit nie, behalwe vir die `release_agent` kenmerk, wat, indien verkeerd geconfigureer, potensieel misbruik kan word vir ongeoorloofde toegang. -**Capability Drop** +**Vermogen Val** -- **Importance**: It's a crucial security feature for process isolation. -- **Functionality**: It restricts the actions a root process can perform by dropping certain capabilities. Even if a process runs with root privileges, lacking the necessary capabilities prevents it from executing privileged actions, as the syscalls will fail due to insufficient permissions. - -These are the **remaining capabilities** after the process drop the others: +- **Belangrikheid**: Dit is 'n noodsaaklike sekuriteitskenmerk vir proses isolasie. +- **Funksionaliteit**: Dit beperk die aksies wat 'n wortel proses kan uitvoer deur sekere vermogens te laat val. Selfs al loop 'n proses met wortelregte, verhoed die gebrek aan die nodige vermogens dat dit bevoorregte aksies kan uitvoer, aangesien die syscalls sal misluk weens onvoldoende toestemmings. +Dit is die **oorblywende vermogens** nadat die proses die ander laat val het: ``` Current: cap_chown,cap_dac_override,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_setpcap,cap_net_bind_service,cap_net_raw,cap_sys_chroot,cap_mknod,cap_audit_write,cap_setfcap=ep ``` - **Seccomp** -It's enabled by default in Docker.

### Namespaces -**Namespaces** are a feature of the Linux kernel that **partitions kernel resources** such that one set of **processes** **sees** one set of **resources** while **another** set of **processes** sees a **different** set of resources.

Resources may exist in multiple spaces. +**Namespaces** is 'n kenmerk van die Linux-kern wat **kernhulpbronne** partitioneer sodat een stel **prosesse** **een stel hulpbronne** sien terwyl **'n ander** stel **prosesse** 'n **verskillende** stel hulpbronne sien.

Die versoek bevat die gebruiker (oproeper) en opdrag konteks. Die **plugin** is verantwoordelik om te besluit of die versoek **toegelaat** of **ontken** moet word. -The sequence diagrams below depict an allow and deny authorization flow: +Die volgorde diagramme hieronder toon 'n toelaat en ontken autorisasie vloei: ![Authorization Allow flow](https://docs.docker.com/engine/extend/images/authz_allow.png) ![Authorization Deny flow](https://docs.docker.com/engine/extend/images/authz_deny.png) -Each request sent to the plugin **includes the authenticated user, the HTTP headers, and the request/response body**. Only the **user name** and the **authentication method** used are passed to the plugin. Most importantly, **no** user **credentials** or tokens are passed. Finally, **not all request/response bodies are sent** to the authorization plugin. Only those request/response bodies where the `Content-Type` is either `text/*` or `application/json` are sent. +Elke versoek wat aan die plugin gestuur word, **sluit die geverifieerde gebruiker, die HTTP koptekste, en die versoek/antwoord liggaam** in. Slegs die **gebruikersnaam** en die **authentikasie metode** wat gebruik is, word aan die plugin deurgegee. Belangrik, **geen** gebruikers **akkrediteer** of tokens word deurgegee nie. Laastens, **nie alle versoek/antwoord liggame word** aan die autorisasie plugin gestuur nie. Slegs daardie versoek/antwoord liggame waar die `Content-Type` of `text/*` of `application/json` is, word gestuur. -For commands that can potentially hijack the HTTP connection (`HTTP Upgrade`), such as `exec`, the authorization plugin is only called for the initial HTTP requests. Once the plugin approves the command, authorization is not applied to the rest of the flow. Specifically, the streaming data is not passed to the authorization plugins. For commands that return chunked HTTP response, such as `logs` and `events`, only the HTTP request is sent to the authorization plugins. +Vir opdragte wat moontlik die HTTP verbinding kan oorneem (`HTTP Upgrade`), soos `exec`, word die autorisasie plugin slegs vir die aanvanklike HTTP versoeke aangeroep. Sodra die plugin die opdrag goedkeur, word autorisasie nie op die res van die vloei toegepas nie. Spesifiek, die stroomdata word nie aan die autorisasie plugins deurgegee nie. Vir opdragte wat gekapte HTTP antwoorde teruggee, soos `logs` en `events`, word slegs die HTTP versoek aan die autorisasie plugins gestuur. -During request/response processing, some authorization flows might need to do additional queries to the Docker daemon. To complete such flows, plugins can call the daemon API similar to a regular user. To enable these additional queries, the plugin must provide the means for an administrator to configure proper authentication and security policies. +Tydens versoek/antwoord verwerking, mag sommige autorisasie vloei addisionele navrae aan die Docker daemon benodig. Om sulke vloei te voltooi, kan plugins die daemon API aanroep soos 'n gewone gebruiker. Om hierdie addisionele navrae moontlik te maak, moet die plugin die middele verskaf vir 'n administrateur om behoorlike authentikasie en sekuriteitsbeleide te konfigureer. -## Several Plugins +## Verskeie Plugins -You are responsible for **registering** your **plugin** as part of the Docker daemon **startup**.

To investigate a shell's cgroup configuration, one should examine the **/proc/self/cgroup** file, which reveals the shell's cgroup. Then, by navigating to the **/sys/fs/cgroup** (or **`/sys/fs/cgroup/unified`**) directory and locating a directory that shares the cgroup's name, one can observe various settings and resource usage information pertinent to the cgroup. +Die lêerstelsel word tipies gebruik om toegang te verkry tot **cgroups**, wat afwyk van die Unix-sisteemoproepinterface wat tradisioneel vir kerninteraksies gebruik word. Om 'n skulp se cgroup-konfigurasie te ondersoek, moet 'n mens die **/proc/self/cgroup** lêer nagaan, wat die skulp se cgroup onthul. Dan, deur na die **/sys/fs/cgroup** (of **`/sys/fs/cgroup/unified`**) gids te navigeer en 'n gids te vind wat die cgroup se naam deel, kan 'n mens verskeie instellings en hulpbronverbruikinligting wat relevant is tot die cgroup, waarneem. ![Cgroup Filesystem](<../../../images/image (1128).png>) -The key interface files for cgroups are prefixed with **cgroup**. The **cgroup.procs** file, which can be viewed with standard commands like cat, lists the processes within the cgroup. Another file, **cgroup.threads**, includes thread information. +Die sleutelinterfaiselêers vir cgroups is met **cgroup** voorafgegaan. Die **cgroup.procs** lêer, wat met standaardopdragte soos cat beskou kan word, lys die prosesse binne die cgroup. 'n Ander lêer, **cgroup.threads**, sluit draad-inligting in. ![Cgroup Procs](<../../../images/image (281).png>) -Cgroups managing shells typically encompass two controllers that regulate memory usage and process count. To interact with a controller, files bearing the controller's prefix should be consulted. For instance, **pids.current** would be referenced to ascertain the count of threads in the cgroup. +Cgroups wat skulp bestuur, sluit tipies twee beheerders in wat geheuegebruik en prosesgetal reguleer. Om met 'n beheerder te kommunikeer, moet lêers met die beheerder se voorvoegsel geraadpleeg word. Byvoorbeeld, **pids.current** sou geraadpleeg word om die aantal drade in die cgroup te bepaal. ![Cgroup Memory](<../../../images/image (677).png>) -The indication of **max** in a value suggests the absence of a specific limit for the cgroup. However, due to the hierarchical nature of cgroups, limits might be imposed by a cgroup at a lower level in the directory hierarchy. +Die aanduiding van **max** in 'n waarde dui op die afwesigheid van 'n spesifieke limiet vir die cgroup. egter, as gevolg van die hiërargiese aard van cgroups, mag limiete opgelê word deur 'n cgroup op 'n laer vlak in die gids hiërargie. -### Manipulating and Creating cgroups - -Processes are assigned to cgroups by **writing their Process ID (PID) to the `cgroup.procs` file**.

To set a maximum of 3,000 PIDs for a cgroup: - +Net so, **om cgroup-attribuutte te wysig, soos om 'n PID-limiet in te stel**, word dit gedoen deur die verlangde waarde na die relevante lêer te skryf.

Alhoewel cgroups sonder aktiewe prosesse met `rmdir` verwyder kan word, wees bewus van sekere beperkings: -**Creating new cgroups** involves making a new subdirectory within the cgroup hierarchy, which prompts the kernel to automatically generate necessary interface files. Though cgroups without active processes can be removed with `rmdir`, be aware of certain constraints: - -- **Processes can only be placed in leaf cgroups** (i.e., the most nested ones in a hierarchy). -- **A cgroup cannot possess a controller absent in its parent**. -- **Controllers for child cgroups must be explicitly declared** in the `cgroup.subtree_control` file. For example, to enable CPU and PID controllers in a child cgroup: - +- **Prosesse kan slegs in blaar cgroups geplaas word** (d.w.s., die mees geneste in 'n hiërargie). +- **'n cgroup kan nie 'n kontroleerder hê wat nie in sy ouer is nie**. +- **Kontroleerders vir kind cgroups moet eksplisiet verklaar word** in die `cgroup.subtree_control` lêer.

Dit kan gebruik word om prosesse uit systemd bestuur te verwyder. -The **root cgroup** is an exception to these rules, allowing direct process placement. This can be used to remove processes from systemd management. +**Monitering van CPU-gebruik** binne 'n cgroup is moontlik deur die `cpu.stat` lêer, wat die totale CPU-tyd wat verbruik is, vertoon, nuttig vir die opsporing van gebruik oor 'n diens se subprosesse: -**Monitoring CPU usage** within a cgroup is possible through the `cpu.stat` file, displaying total CPU time consumed, helpful for tracking usage across a service's subprocesses: +

In case of absence of the RDMA controller, it's suggested to use the `memory` cgroup controller as an alternative. - +1. **Bereid die Omgewing Voor:** +- 'n Gids `/tmp/cgrp` word geskep om as 'n monteerpunt vir die cgroup te dien. +- Die RDMA cgroup-beheerder word op hierdie gids gemonteer. In die geval van afwesigheid van die RDMA-beheerder, word dit voorgestel om die `memory` cgroup-beheerder as 'n alternatief te gebruik. ```shell mkdir /tmp/cgrp && mount -t cgroup -o rdma cgroup /tmp/cgrp && mkdir /tmp/cgrp/x ``` - -2. **Set Up the Child Cgroup:** - - A child cgroup named "x" is created within the mounted cgroup directory. - - Notifications are enabled for the "x" cgroup by writing 1 to its notify_on_release file. - +2. **Stel die Kind Cgroup op:** +- 'n Kind cgroup met die naam "x" word binne die gemonteerde cgroup-gids geskep. +- Kennisgewings word geaktiveer vir die "x" cgroup deur 1 in sy notify_on_release-lêer te skryf. ```shell echo 1 > /tmp/cgrp/x/notify_on_release ``` - -3. **Configure the Release Agent:** - - The path of the container on the host is obtained from the /etc/mtab file. - - The release_agent file of the cgroup is then configured to execute a script named /cmd located at the acquired host path. - +3. **Konfigureer die Release Agent:** +- Die pad van die houer op die gasheer word verkry uit die /etc/mtab lêer. +- Die release_agent lêer van die cgroup word dan gekonfigureer om 'n skrif genaamd /cmd uit te voer wat op die verkryde gasheerpad geleë is. ```shell host_path=`sed -n 's/.*\perdir=\([^,]*\).*/\1/p' /etc/mtab` echo "$host_path/cmd" > /tmp/cgrp/release_agent ``` - -4. **Create and Configure the /cmd Script:** - - The /cmd script is created inside the container and is configured to execute ps aux, redirecting the output to a file named /output in the container.

This bypasses the need to know the container's filesystem path on the host. -2. **PID Bashing:** A brute force approach is employed to search through PIDs on the host. This is done by sequentially checking for the presence of a specific file at `/proc//root/`. When the file is found, it indicates that the corresponding PID belongs to a process running inside the target container. -3. **Triggering Execution:** The guessed PID path is written to the `cgroups release_agent` file. This action triggers the execution of the `release_agent`. The success of this step is confirmed by checking for the creation of an output file. +1. **Proses ID's (PIDs) Vind:** Deur die `/proc//root` simboliese skakel in die Linux pseudo-lêerstelsel te gebruik, kan enige lêer binne die houer toeganklik gemaak word relatief tot die gasheer se lêerstelsel. Dit omseil die behoefte om die houer se lêerstelsel pad op die gasheer te ken. +2. **PID Bashing:** 'n Brute force benadering word gebruik om deur PIDs op die gasheer te soek. Dit word gedoen deur die teenwoordigheid van 'n spesifieke lêer by `/proc//root/` sekwensieel na te gaan. Wanneer die lêer gevind word, dui dit aan dat die ooreenstemmende PID aan 'n proses behoort wat binne die teikenhouer loop. +3. **Triggering Uitvoering:** Die geraamde PID pad word na die `cgroups release_agent` lêer geskryf. Hierdie aksie aktiveer die uitvoering van die `release_agent`. Die sukses van hierdie stap word bevestig deur na die skepping van 'n uitvoer lêer te kyk. -### Exploitation Process +### Exploitasie Proses -The exploitation process involves a more detailed set of actions, aiming to execute a payload on the host by guessing the correct PID of a process running inside the container. Here's how it unfolds: +Die exploitasie proses behels 'n meer gedetailleerde stel aksies, met die doel om 'n payload op die gasheer uit te voer deur die korrekte PID van 'n proses wat binne die houer loop te raai. Hier is hoe dit ontvou: -1. **Initialize Environment:** A payload script (`payload.sh`) is prepared on the host, and a unique directory is created for cgroup manipulation. -2. **Prepare Payload:** The payload script, which contains the commands to be executed on the host, is written and made executable. -3. **Set Up Cgroup:** The cgroup is mounted and configured. The `notify_on_release` flag is set to ensure that the payload executes when the cgroup is released. -4. **Brute Force PID:** A loop iterates through potential PIDs, writing each guessed PID to the `release_agent` file. This effectively sets the payload script as the `release_agent`. -5. **Trigger and Check Execution:** For each PID, the cgroup's `cgroup.procs` is written to, triggering the execution of the `release_agent` if the PID is correct. The loop continues until the output of the payload script is found, indicating successful execution. - -PoC from the blog post: +1. **Begin Omgewing:** 'n Payload skrip (`payload.sh`) word op die gasheer voorberei, en 'n unieke gids word geskep vir cgroup manipulasie. +2. **Bereid Payload Voor:** Die payload skrip, wat die opdragte bevat wat op die gasheer uitgevoer moet word, word geskryf en uitvoerbaar gemaak. +3. **Stel Cgroup Op:** Die cgroup word gemonteer en geconfigureer. Die `notify_on_release` vlag word gestel om te verseker dat die payload uitgevoer word wanneer die cgroup vrygestel word. +4. **Brute Force PID:** 'n Lus herhaal deur potensiële PIDs, en skryf elke geraamde PID na die `release_agent` lêer. Dit stel effektief die payload skrip as die `release_agent`. +5. **Trigger en Kontroleer Uitvoering:** Vir elke PID, word die cgroup se `cgroup.procs` geskryf, wat die uitvoering van die `release_agent` aktiveer as die PID korrek is.

Cgroups, short for **control groups**, are a kernel feature that allows organizing processes into hierarchical groups to manage and enforce **limits on system resources** like CPU, memory, and I/O. +'n cgroup namespace is 'n Linux-kernfunksie wat **isolatie van cgroup hiërargieë vir prosesse wat binne 'n namespace loop** bied. Cgroups, kort vir **kontrole groepe**, is 'n kernfunksie wat toelaat om prosesse in hiërargiese groepe te organiseer om **grense op stelselhulpbronne** soos CPU, geheue en I/O te bestuur en af te dwing. -While cgroup namespaces are not a separate namespace type like the others we discussed earlier (PID, mount, network, etc.), they are related to the concept of namespace isolation. **Cgroup namespaces virtualize the view of the cgroup hierarchy**, so that processes running within a cgroup namespace have a different view of the hierarchy compared to processes running in the host or other namespaces. +Terwyl cgroup namespaces nie 'n aparte namespace tipe is soos die ander wat ons vroeër bespreek het nie (PID, mount, netwerk, ens.), is hulle verwant aan die konsep van namespace isolasie. **Cgroup namespaces virtualiseer die siening van die cgroup hiërargie**, sodat prosesse wat binne 'n cgroup namespace loop 'n ander siening van die hiërargie het in vergelyking met prosesse wat in die gasheer of ander namespaces loop. -### How it works: +### Hoe dit werk: -1. When a new cgroup namespace is created, **it starts with a view of the cgroup hierarchy based on the cgroup of the creating process**. This means that processes running in the new cgroup namespace will only see a subset of the entire cgroup hierarchy, limited to the cgroup subtree rooted at the creating process's cgroup. -2. Processes within a cgroup namespace will **see their own cgroup as the root of the hierarchy**. This means that, from the perspective of processes inside the namespace, their own cgroup appears as the root, and they cannot see or access cgroups outside of their own subtree. -3. Cgroup namespaces do not directly provide isolation of resources; **they only provide isolation of the cgroup hierarchy view**. **Resource control and isolation are still enforced by the cgroup** subsystems (e.g., cpu, memory, etc.) themselves. +1. Wanneer 'n nuwe cgroup namespace geskep word, **begin dit met 'n siening van die cgroup hiërargie gebaseer op die cgroup van die skepende proses**. Dit beteken dat prosesse wat in die nuwe cgroup namespace loop slegs 'n subset van die hele cgroup hiërargie sal sien, beperk tot die cgroup subboom wat gegrond is op die skepende proses se cgroup. +2. Prosesse binne 'n cgroup namespace sal **hulle eie cgroup as die wortel van die hiërargie sien**. Dit beteken dat, vanuit die perspektief van prosesse binne die namespace, hulle eie cgroup as die wortel verskyn, en hulle kan nie cgroups buite hul eie subboom sien of toegang daartoe kry nie. +3. Cgroup namespaces bied nie direk isolasie van hulpbronne nie; **hulle bied slegs isolasie van die cgroup hiërargie siening**. **Hulpbronbeheer en isolasie word steeds afgedwing deur die cgroup** subsisteme (bv., cpu, geheue, ens.) self. -For more information about CGroups check: +Vir meer inligting oor CGroups kyk: {{#ref}} ../cgroups.md {{#endref}} -## Lab: +## Laboratorium: -### Create different Namespaces +### Skep verskillende Namespaces #### CLI - ```bash sudo unshare -C [--mount-proc] /bin/bash ``` - -By mounting a new instance of the `/proc` filesystem if you use the param `--mount-proc`, you ensure that the new mount namespace has an **accurate and isolated view of the process information specific to that namespace**. +Deur 'n nuwe instansie van die `/proc` lêerstelsel te monteer as jy die parameter `--mount-proc` gebruik, verseker jy dat die nuwe monteernaamruimte 'n **akkurate en geïsoleerde siening van die prosesinligting spesifiek vir daardie naamruimte** het.
-Error: bash: fork: Cannot allocate memory +Fout: bash: fork: Kan nie geheue toewys nie -When `unshare` is executed without the `-f` option, an error is encountered due to the way Linux handles new PID (Process ID) namespaces. The key details and the solution are outlined below: +Wanneer `unshare` sonder die `-f` opsie uitgevoer word, word 'n fout ondervind weens die manier waarop Linux nuwe PID (Proses ID) naamruimtes hanteer. Die sleutelbesonderhede en die oplossing word hieronder uiteengesit: -1. **Problem Explanation**: +1. **Probleemverklaring**: - - The Linux kernel allows a process to create new namespaces using the `unshare` system call. However, the process that initiates the creation of a new PID namespace (referred to as the "unshare" process) does not enter the new namespace; only its child processes do. - - Running `%unshare -p /bin/bash%` starts `/bin/bash` in the same process as `unshare`. Consequently, `/bin/bash` and its child processes are in the original PID namespace. - - The first child process of `/bin/bash` in the new namespace becomes PID 1. When this process exits, it triggers the cleanup of the namespace if there are no other processes, as PID 1 has the special role of adopting orphan processes. The Linux kernel will then disable PID allocation in that namespace. +- Die Linux-kern laat 'n proses toe om nuwe naamruimtes te skep met die `unshare` stelselaanroep. Die proses wat die skepping van 'n nuwe PID naamruimte inisieer (genoem die "unshare" proses) gaan egter nie in die nuwe naamruimte in nie; slegs sy kindproses gaan. +- Die uitvoering van `%unshare -p /bin/bash%` begin `/bin/bash` in dieselfde proses as `unshare`. Gevolglik is `/bin/bash` en sy kindproses in die oorspronklike PID naamruimte. +- Die eerste kindproses van `/bin/bash` in die nuwe naamruimte word PID 1. Wanneer hierdie proses verlaat, aktiveer dit die opruiming van die naamruimte as daar geen ander prosesse is nie, aangesien PID 1 die spesiale rol het om weeskindprosesse aan te neem. Die Linux-kern sal dan PID-toewysing in daardie naamruimte deaktiveer. -2. **Consequence**: +2. **Gevolg**: - - The exit of PID 1 in a new namespace leads to the cleaning of the `PIDNS_HASH_ADDING` flag. This results in the `alloc_pid` function failing to allocate a new PID when creating a new process, producing the "Cannot allocate memory" error. +- Die uitgang van PID 1 in 'n nuwe naamruimte lei tot die opruiming van die `PIDNS_HASH_ADDING` vlag. Dit lei tot die `alloc_pid` funksie wat misluk om 'n nuwe PID toe te wys wanneer 'n nuwe proses geskep word, wat die "Kan nie geheue toewys nie" fout veroorsaak. -3. **Solution**: - - The issue can be resolved by using the `-f` option with `unshare`. This option makes `unshare` fork a new process after creating the new PID namespace. - - Executing `%unshare -fp /bin/bash%` ensures that the `unshare` command itself becomes PID 1 in the new namespace. `/bin/bash` and its child processes are then safely contained within this new namespace, preventing the premature exit of PID 1 and allowing normal PID allocation. +3. **Oplossing**: +- Die probleem kan opgelos word deur die `-f` opsie saam met `unshare` te gebruik. Hierdie opsie maak dat `unshare` 'n nuwe proses fork nadat die nuwe PID naamruimte geskep is. +- Die uitvoering van `%unshare -fp /bin/bash%` verseker dat die `unshare` opdrag self PID 1 in die nuwe naamruimte word. `/bin/bash` en sy kindproses is dan veilig binne hierdie nuwe naamruimte, wat die voortydige uitgang van PID 1 voorkom en normale PID-toewysing toelaat. -By ensuring that `unshare` runs with the `-f` flag, the new PID namespace is correctly maintained, allowing `/bin/bash` and its sub-processes to operate without encountering the memory allocation error. +Deur te verseker dat `unshare` met die `-f` vlag loop, word die nuwe PID naamruimte korrek gehandhaaf, wat toelaat dat `/bin/bash` en sy sub-prosesse kan werk sonder om die geheue toewysing fout te ondervind.

This is particularly useful in containerization, where process isolation is essential for security and resource management. +Die PID (Proses IDentifiseerder) naamruimte is 'n kenmerk in die Linux-kern wat proses-isolasie bied deur 'n groep prosesse in staat te stel om hul eie stel unieke PID's te hê, apart van die PID's in ander naamruimtes. Dit is veral nuttig in houers, waar proses-isolasie noodsaaklik is vir sekuriteit en hulpbronbestuur. -When a new PID namespace is created, the first process in that namespace is assigned PID 1. This process becomes the "init" process of the new namespace and is responsible for managing other processes within the namespace. Each subsequent process created within the namespace will have a unique PID within that namespace, and these PIDs will be independent of PIDs in other namespaces. +Wanneer 'n nuwe PID naamruimte geskep word, word die eerste proses in daardie naamruimte aan PID 1 toegeken. Hierdie proses word die "init" proses van die nuwe naamruimte en is verantwoordelik vir die bestuur van ander prosesse binne die naamruimte. Elke daaropvolgende proses wat binne die naamruimte geskep word, sal 'n unieke PID binne daardie naamruimte hê, en hierdie PID's sal onafhanklik wees van PID's in ander naamruimtes. -From the perspective of a process within a PID namespace, it can only see other processes in the same namespace. It is not aware of processes in other namespaces, and it cannot interact with them using traditional process management tools (e.g., `kill`, `wait`, etc.).

Dit is nie bewus van prosesse in ander naamruimtes nie, en dit kan nie met hulle interaksie hê nie met behulp van tradisionele prosesbestuur gereedskap (bv. `kill`, `wait`, ens.).

When a new process is created (e.g., by using the `clone()` system call), the process can be assigned to a new or existing PID namespace. **If a new namespace is created, the process becomes the "init" process of that namespace**. -2. The **kernel** maintains a **mapping between the PIDs in the new namespace and the corresponding PIDs** in the parent namespace (i.e., the namespace from which the new namespace was created). This mapping **allows the kernel to translate PIDs when necessary**, such as when sending signals between processes in different namespaces. -3. **Processes within a PID namespace can only see and interact with other processes in the same namespace**. They are not aware of processes in other namespaces, and their PIDs are unique within their namespace. -4. When a **PID namespace is destroyed** (e.g., when the "init" process of the namespace exits), **all processes within that namespace are terminated**. This ensures that all resources associated with the namespace are properly cleaned up. +1. Wanneer 'n nuwe proses geskep word (bv. deur die `clone()` stelselskakel te gebruik), kan die proses aan 'n nuwe of bestaande PID naamruimte toegeken word. **As 'n nuwe naamruimte geskep word, word die proses die "init" proses van daardie naamruimte**. +2. Die **kern** handhaaf 'n **kaart tussen die PID's in die nuwe naamruimte en die ooreenstemmende PID's** in die ouer naamruimte (d.w.s. die naamruimte waaruit die nuwe naamruimte geskep is).

Within a user namespace, **processes can have full root privileges (UID 0) for operations inside the namespace**, while still having limited privileges outside the namespace.

-Error: bash: fork: Cannot allocate memory +Fout: bash: fork: Kan nie geheue toewys nie -When `unshare` is executed without the `-f` option, an error is encountered due to the way Linux handles new PID (Process ID) namespaces. The key details and the solution are outlined below: +Wanneer `unshare` sonder die `-f` opsie uitgevoer word, word 'n fout ondervind weens die manier waarop Linux nuwe PID (Proses ID) naamruimtes hanteer. Die sleutelbesonderhede en die oplossing word hieronder uiteengesit: -1. **Problem Explanation**: +1. **Probleemverklaring**: - - The Linux kernel allows a process to create new namespaces using the `unshare` system call. However, the process that initiates the creation of a new PID namespace (referred to as the "unshare" process) does not enter the new namespace; only its child processes do. - - Running `%unshare -p /bin/bash%` starts `/bin/bash` in the same process as `unshare`. Consequently, `/bin/bash` and its child processes are in the original PID namespace. - - The first child process of `/bin/bash` in the new namespace becomes PID 1. When this process exits, it triggers the cleanup of the namespace if there are no other processes, as PID 1 has the special role of adopting orphan processes. The Linux kernel will then disable PID allocation in that namespace. +- Die Linux-kern laat 'n proses toe om nuwe naamruimtes te skep met die `unshare` stelselaanroep. Die proses wat die skepping van 'n nuwe PID naamruimte begin (genoem die "unshare" proses) gaan egter nie in die nuwe naamruimte in nie; slegs sy kindprosesse doen. +- Die uitvoering van `%unshare -p /bin/bash%` begin `/bin/bash` in dieselfde proses as `unshare`. Gevolglik is `/bin/bash` en sy kindprosesse in die oorspronklike PID naamruimte. +- Die eerste kindproses van `/bin/bash` in die nuwe naamruimte word PID 1. Wanneer hierdie proses verlaat, veroorsaak dit die opruiming van die naamruimte as daar geen ander prosesse is nie, aangesien PID 1 die spesiale rol het om weeskindprosesse aan te neem. Die Linux-kern sal dan PID-toewysing in daardie naamruimte deaktiveer. -2. **Consequence**: +2. **Gevolg**: - - The exit of PID 1 in a new namespace leads to the cleaning of the `PIDNS_HASH_ADDING` flag. This results in the `alloc_pid` function failing to allocate a new PID when creating a new process, producing the "Cannot allocate memory" error. +- Die uitgang van PID 1 in 'n nuwe naamruimte lei tot die opruiming van die `PIDNS_HASH_ADDING` vlag. Dit lei tot die `alloc_pid` funksie wat misluk om 'n nuwe PID toe te wys wanneer 'n nuwe proses geskep word, wat die "Kan nie geheue toewys nie" fout veroorsaak. -3. **Solution**: - - The issue can be resolved by using the `-f` option with `unshare`. This option makes `unshare` fork a new process after creating the new PID namespace. - - Executing `%unshare -fp /bin/bash%` ensures that the `unshare` command itself becomes PID 1 in the new namespace. `/bin/bash` and its child processes are then safely contained within this new namespace, preventing the premature exit of PID 1 and allowing normal PID allocation. +3. **Oplossing**: +- Die probleem kan opgelos word deur die `-f` opsie saam met `unshare` te gebruik.

Useful for maintaining certain privileges across process spawns. - - **Restrictions**: A process cannot gain capabilities that its parent did not possess. +- **Doel**: Verteenwoordig die werklike vermoëns wat 'n proses op enige oomblik gebruik. +- **Funksionaliteit**: Dit is die stel vermoëns wat deur die kernel nagegaan word om toestemming vir verskeie operasies te verleen. Vir lêers kan hierdie stel 'n vlag wees wat aandui of die lêer se toegelate vermoëns as effektief beskou moet word. +- **Belangrikheid**: Die effektiewe stel is van kardinale belang vir onmiddellike bevoegdheidstoetsing, wat as die aktiewe stel van vermoëns dien wat 'n proses kan gebruik. -2. **Effective (CapEff)**: +3. **Toegelaat (CapPrm)**: - - **Purpose**: Represents the actual capabilities a process is utilizing at any moment. - - **Functionality**: It's the set of capabilities checked by the kernel to grant permission for various operations. For files, this set can be a flag indicating if the file's permitted capabilities are to be considered effective. - - **Significance**: The effective set is crucial for immediate privilege checks, acting as the active set of capabilities a process can use. +- **Doel**: Definieer die maksimum stel vermoëns wat 'n proses kan besit. +- **Funksionaliteit**: 'n Proses kan 'n vermoë van die toegelate stel na sy effektiewe stel verhoog, wat dit die vermoë gee om daardie vermoë te gebruik. Dit kan ook vermoëns uit sy toegelate stel laat val. +- **Grens**: Dit dien as 'n boonste limiet vir die vermoëns wat 'n proses kan hê, wat verseker dat 'n proses nie sy vooraf gedefinieerde bevoegdheidsscope oorskry nie. -3. **Permitted (CapPrm)**: +4. **Beperking (CapBnd)**: - - **Purpose**: Defines the maximum set of capabilities a process can possess. - - **Functionality**: A process can elevate a capability from the permitted set to its effective set, giving it the ability to use that capability. It can also drop capabilities from its permitted set. - - **Boundary**: It acts as an upper limit for the capabilities a process can have, ensuring a process doesn't exceed its predefined privilege scope. - -4. **Bounding (CapBnd)**: - - - **Purpose**: Puts a ceiling on the capabilities a process can ever acquire during its lifecycle. - - **Functionality**: Even if a process has a certain capability in its inheritable or permitted set, it cannot acquire that capability unless it's also in the bounding set. - - **Use-case**: This set is particularly useful for restricting a process's privilege escalation potential, adding an extra layer of security. - -5. **Ambient (CapAmb)**: - - **Purpose**: Allows certain capabilities to be maintained across an `execve` system call, which typically would result in a full reset of the process's capabilities. - - **Functionality**: Ensures that non-SUID programs that don't have associated file capabilities can retain certain privileges. - - **Restrictions**: Capabilities in this set are subject to the constraints of the inheritable and permitted sets, ensuring they don't exceed the process's allowed privileges. +- **Doel**: Plaas 'n plafon op die vermoëns wat 'n proses ooit kan verkry gedurende sy lewensiklus. +- **Funksionaliteit**: Selfs al het 'n proses 'n sekere vermoë in sy geërfde of toegelate stel, kan dit nie daardie vermoë verkry nie tensy dit ook in die beperkende stel is. +- **Gebruiksgval**: Hierdie stel is veral nuttig om 'n proses se bevoegdheidseskalering potensiaal te beperk, wat 'n ekstra laag van sekuriteit toevoeg. +5. **Omgewings (CapAmb)**: +- **Doel**: Laat sekere vermoëns toe om oor 'n `execve` stelselsoproep gehandhaaf te word, wat tipies 'n volle reset van die proses se vermoëns sou veroorsaak. +- **Funksionaliteit**: Verseker dat nie-SUID programme wat nie geassosieerde lêer vermoëns het nie, sekere bevoegdhede kan behou. +- **Beperkings**: Vermoëns in hierdie stel is onderhewig aan die beperkings van die geërfde en toegelate stelle, wat verseker dat hulle nie die proses se toegelate bevoegdhede oorskry nie. ```python # Code to demonstrate the interaction of different capability sets might look like this: # Note: This is pseudo-code for illustrative purposes only. def manage_capabilities(process): - if process.has_capability('cap_setpcap'): - process.add_capability_to_set('CapPrm', 'new_capability') - process.limit_capabilities('CapBnd') - process.preserve_capabilities_across_execve('CapAmb') +if process.has_capability('cap_setpcap'): +process.add_capability_to_set('CapPrm', 'new_capability') +process.limit_capabilities('CapBnd') +process.preserve_capabilities_across_execve('CapAmb') ``` - -For further information check: +Vir verdere inligting, kyk: - [https://blog.container-solutions.com/linux-capabilities-why-they-exist-and-how-they-work](https://blog.container-solutions.com/linux-capabilities-why-they-exist-and-how-they-work) - [https://blog.ploetzli.ch/2014/understanding-linux-capabilities/](https://blog.ploetzli.ch/2014/understanding-linux-capabilities/) -## Processes & Binaries Capabilities +## Prosesse & Binaries Vermoëns -### Processes Capabilities +### Prosesse Vermoëns -To see the capabilities for a particular process, use the **status** file in the /proc directory.

Its primary use is for file searching or reading purposes. However, it also allows a process to use the `open_by_handle_at(2)` function, which can access any file, including those outside the process's mount namespace. The handle used in `open_by_handle_at(2)` is supposed to be a non-transparent identifier obtained through `name_to_handle_at(2)`, but it can include sensitive information like inode numbers that are vulnerable to tampering. The potential for exploitation of this capability, particularly in the context of Docker containers, was demonstrated by Sebastian Krahmer with the shocker exploit, as analyzed [here](https://medium.com/@fun_cuddles/docker-breakout-exploit-analysis-a274fff0e6b3). -**This means that you can** **bypass can bypass file read permission checks and directory read/execute permission checks.** +[**CAP_DAC_READ_SEARCH**](https://man7.org/linux/man-pages/man7/capabilities.7.html) stel 'n proses in staat om **toestemmings vir die lees van lêers en vir die lees en uitvoer van gidse te omseil**. Die primêre gebruik daarvan is vir lêer soek of leesdoeleindes. Dit stel egter ook 'n proses in staat om die `open_by_handle_at(2)` funksie te gebruik, wat enige lêer kan benader, insluitend dié buite die proses se monteernaamruimte. Die handvatsel wat in `open_by_handle_at(2)` gebruik word, behoort 'n nie-deursigtige identifiseerder te wees wat verkry is deur `name_to_handle_at(2)`, maar dit kan sensitiewe inligting insluit soos inode-nommers wat kwesbaar is vir manipulasie. Die potensiaal vir die uitbuiting van hierdie vermoë, veral in die konteks van Docker-konteiners, is deur Sebastian Krahmer met die shocker exploit gedemonstreer, soos geanaliseer [hier](https://medium.com/@fun_cuddles/docker-breakout-exploit-analysis-a274fff0e6b3). +**Dit beteken dat jy kan** **toestemmings vir lêer lees en gidse lees/uitvoer kan omseil.** -**Example with binary** - -The binary will be able to read any file.

Sedert Linux 2.6.39 is die standaard vir `kptr_restrict` 0, wat beteken dat kernadresse blootgestel word, hoewel baie verspreidings dit op 1 (versteek adresse behalwe van uid 0) of 2 (altyd adresse versteek) vir sekuriteitsredes stel. -Additionally, **CAP_SYSLOG** allows accessing `dmesg` output when `dmesg_restrict` is set to 1.

However, a process can only modify capabilities that it possesses in its own permitted set, ensuring it cannot elevate another process's privileges beyond its own. Recent kernel updates have tightened these rules, restricting `CAP_SETPCAP` to only diminish the capabilities within its own or its descendants' permitted sets, aiming to mitigate security risks. Usage requires having `CAP_SETPCAP` in the effective set and the target capabilities in the permitted set, utilizing `capset()` for modifications. This summarizes the core function and limitations of `CAP_SETPCAP`, highlighting its role in privilege management and security enhancement. +**CAP_SETPCAP** stel 'n proses in staat om **die vermoëns van 'n ander proses te verander**, wat die toevoeging of verwydering van vermoëns uit die effektiewe, erfbare en toegelate stelle moontlik maak. 'n Proses kan egter slegs vermoëns wat dit in sy eie toegelate stel het, wysig, wat verseker dat dit nie die voorregte van 'n ander proses bo sy eie kan verhoog nie. Onlangs het kernopdaterings hierdie reëls verskerp, wat `CAP_SETPCAP` beperk tot slegs die vermindering van die vermoëns binne sy eie of sy afstammelinge se toegelate stelle, met die doel om sekuriteitsrisiko's te verminder. Gebruik vereis dat `CAP_SETPCAP` in die effektiewe stel en die teikenvermoëns in die toegelate stel is, met `capset()` vir wysigings. Dit som die kernfunksie en beperkings van `CAP_SETPCAP` op, wat sy rol in voorregbestuur en sekuriteitsverbetering beklemtoon. -**`CAP_SETPCAP`** is a Linux capability that allows a process to **modify the capability sets of another process**. It grants the ability to add or remove capabilities from the effective, inheritable, and permitted capability sets of other processes. However, there are certain restrictions on how this capability can be used. +**`CAP_SETPCAP`** is 'n Linux vermoë wat 'n proses toelaat om **die vermoëns van 'n ander proses te wysig**. Dit bied die vermoë om vermoëns uit die effektiewe, erfbare en toegelate vermoëns van ander prosesse toe te voeg of te verwyder. Daar is egter sekere beperkings op hoe hierdie vermoë gebruik kan word. -A process with `CAP_SETPCAP` **can only grant or remove capabilities that are in its own permitted capability set**. In other words, a process cannot grant a capability to another process if it does not have that capability itself. This restriction prevents a process from elevating the privileges of another process beyond its own level of privilege. +'n Proses met `CAP_SETPCAP` **kan slegs vermoëns toeken of verwyder wat in sy eie toegelate vermoëns stel is**. Met ander woorde, 'n proses kan nie 'n vermoë aan 'n ander proses toeken as dit nie daardie vermoë self het nie. Hierdie beperking verhoed dat 'n proses die voorregte van 'n ander proses bo sy eie vlak van voorreg verhoog. -Moreover, in recent kernel versions, the `CAP_SETPCAP` capability has been **further restricted**. It no longer allows a process to arbitrarily modify the capability sets of other processes. Instead, it **only allows a process to lower the capabilities in its own permitted capability set or the permitted capability set of its descendants**. This change was introduced to reduce potential security risks associated with the capability. +Boonop is die `CAP_SETPCAP` vermoë in onlangse kernweergawe **verder beperk**. Dit laat nie meer 'n proses toe om arbitrêr die vermoëns van ander prosesse te wysig nie. In plaas daarvan **laat dit slegs 'n proses toe om die vermoëns in sy eie toegelate vermoëns stel of die toegelate vermoëns stel van sy afstammelinge te verlaag**. Hierdie verandering is bekendgestel om potensiële sekuriteitsrisiko's wat met die vermoë verband hou, te verminder. -To use `CAP_SETPCAP` effectively, you need to have the capability in your effective capability set and the target capabilities in your permitted capability set. You can then use the `capset()` system call to modify the capability sets of other processes. +Om `CAP_SETPCAP` effektief te gebruik, moet jy die vermoë in jou effektiewe vermoëns stel en die teikenvermoëns in jou toegelate vermoëns stel hê. Jy kan dan die `capset()` stelselskakel gebruik om die vermoëns van ander prosesse te wysig. -In summary, `CAP_SETPCAP` allows a process to modify the capability sets of other processes, but it cannot grant capabilities that it doesn't have itself. Additionally, due to security concerns, its functionality has been limited in recent kernel versions to only allow reducing capabilities in its own permitted capability set or the permitted capability sets of its descendants. +In samevatting, `CAP_SETPCAP` laat 'n proses toe om die vermoëns van ander prosesse te wysig, maar dit kan nie vermoëns toeken wat dit nie self het nie. Boonop, as gevolg van sekuriteitskwessies, is die funksionaliteit in onlangse kernweergawe beperk om slegs die vermoëns in sy eie toegelate vermoëns stel of die toegelate vermoëns van sy afstammelinge te verminder. -## References +## Verwysings -**Most of these examples were taken from some labs of** [**https://attackdefense.pentesteracademy.com/**](https://attackdefense.pentesteracademy.com), so if you want to practice this privesc techniques I recommend these labs. +**Die meeste van hierdie voorbeelde is geneem uit sommige laboratoriums van** [**https://attackdefense.pentesteracademy.com/**](https://attackdefense.pentesteracademy.com), so as jy hierdie privesc tegnieke wil oefen, beveel ek hierdie laboratoriums aan. -**Other references**: +**Ander verwysings**: - [https://vulp3cula.gitbook.io/hackers-grimoire/post-exploitation/privesc-linux](https://vulp3cula.gitbook.io/hackers-grimoire/post-exploitation/privesc-linux) - [https://www.schutzwerk.com/en/43/posts/linux_container_capabilities/#:\~:text=Inherited%20capabilities%3A%20A%20process%20can,a%20binary%2C%20e.g.%20using%20setcap%20.](https://www.schutzwerk.com/en/43/posts/linux_container_capabilities/) @@ -1700,10 +1532,4 @@ In summary, `CAP_SETPCAP` allows a process to modify the capability sets of othe - [https://labs.withsecure.com/publications/abusing-the-access-to-mount-namespaces-through-procpidroot](https://labs.withsecure.com/publications/abusing-the-access-to-mount-namespaces-through-procpidroot) ​ - -

Hierdie pipelines bestaan uit **invoer**, **filter**, en **uitvoer** fases. 'n Interessante aspek ontstaan wanneer Logstash op 'n gecompromitteerde masjien werk. -### Pipeline Configuration - -Pipelines are configured in the file **/etc/logstash/pipelines.yml**, which lists the locations of the pipeline configurations: +### Pipeline Konfigurasie +Pipelines word geconfigureer in die lêer **/etc/logstash/pipelines.yml**, wat die plekke van die pipeline konfigurasies lys: ```yaml # Define your pipelines here. Multiple pipelines can be defined. # For details on multiple pipelines, refer to the documentation: # https://www.elastic.co/guide/en/logstash/current/multiple-pipelines.html - pipeline.id: main - path.config: "/etc/logstash/conf.d/*.conf" +path.config: "/etc/logstash/conf.d/*.conf" - pipeline.id: example - path.config: "/usr/share/logstash/pipeline/1*.conf" - pipeline.workers: 6 +path.config: "/usr/share/logstash/pipeline/1*.conf" +pipeline.workers: 6 ``` - -This file reveals where the **.conf** files, containing pipeline configurations, are located. When employing an **Elasticsearch output module**, it's common for **pipelines** to include **Elasticsearch credentials**, which often possess extensive privileges due to Logstash's need to write data to Elasticsearch.

Wanneer 'n **Elasticsearch output module** gebruik word, is dit algemeen dat **pyplyne** **Elasticsearch kredensiale** insluit, wat dikwels uitgebreide regte het weens Logstash se behoefte om data na Elasticsearch te skryf. Wildcards in konfigurasiepaaie laat Logstash toe om alle ooreenstemmende pyplyne in die aangewese gids uit te voer. ### Privilege Escalation via Writable Pipelines -To attempt privilege escalation, first identify the user under which the Logstash service is running, typically the **logstash** user. Ensure you meet **one** of these criteria: +Om 'n poging tot privilege-escalasie te doen, identifiseer eers die gebruiker waaronder die Logstash-diens loop, tipies die **logstash** gebruiker.

In the given example, the **whoami** command runs every 120 seconds, with its output directed to **/tmp/output.log**. - -With **config.reload.automatic: true** in **/etc/logstash/logstash.yml**, Logstash will automatically detect and apply new or modified pipeline configurations without needing a restart. If there's no wildcard, modifications can still be made to existing configurations, but caution is advised to avoid disruptions. +Met **config.reload.automatic: true** in **/etc/logstash/logstash.yml**, sal Logstash outomaties nuwe of gewysigde pyplyn konfigurasies opspoor en toepas sonder om 'n herlaai te benodig.

Complementing this, there are multiple 'mdworker' daemons that perform a variety of maintenance tasks, such as indexing different file types (`ps -ef | grep mdworker`). These tasks are made possible through Spotlight importer plugins, or **".mdimporter bundles**", which enable Spotlight to understand and index content across a diverse range of file formats. +Die onderliggende meganisme van Spotlight behels 'n sentrale proses genaamd 'mds', wat staan vir **'metadata server'.** Hierdie proses orkestreer die hele Spotlight diens. Ter aanvulling hiervan, is daar verskeie 'mdworker' daemons wat 'n verskeidenheid onderhoudstake uitvoer, soos die indeksering van verskillende lêertipes (`ps -ef | grep mdworker`). Hierdie take word moontlik gemaak deur Spotlight invoerder plugins, of **".mdimporter bundles**", wat Spotlight in staat stel om inhoud oor 'n diverse reeks lêerformate te verstaan en te indekseer. -The plugins or **`.mdimporter`** bundles are located in the places mentioned previously and if a new bundle appear it's loaded within monute (no need to restart any service). These bundles need to indicate which **file type and extensions they can manage**, this way, Spotlight will use them when a new file with the indicated extension is created. - -It's possible to **find all the `mdimporters`** loaded running: +Die plugins of **`.mdimporter`** bundles is geleë in die plekke wat vroeër genoem is en as 'n nuwe bundle verskyn, word dit binne 'n minuut gelaai (geen behoefte om enige diens te herbegin nie). Hierdie bundles moet aandui watter **lêertipe en uitbreidings hulle kan bestuur**, sodat Spotlight dit sal gebruik wanneer 'n nuwe lêer met die aangeduide uitbreiding geskep word. +Dit is moontlik om **alle `mdimporters`** wat gelaai is, te vind deur te loop: ```bash mdimport -L Paths: id(501) ( - "/System/Library/Spotlight/iWork.mdimporter", - "/System/Library/Spotlight/iPhoto.mdimporter", - "/System/Library/Spotlight/PDF.mdimporter", - [...] +"/System/Library/Spotlight/iWork.mdimporter", +"/System/Library/Spotlight/iPhoto.mdimporter", +"/System/Library/Spotlight/PDF.mdimporter", +[...] ``` - -And for example **/Library/Spotlight/iBooksAuthor.mdimporter** is used to parse these type of files (extensions `.iba` and `.book` among others): - +En byvoorbeeld **/Library/Spotlight/iBooksAuthor.mdimporter** word gebruik om hierdie tipe lêers (uitbreidings `.iba` en `.book` onder andere) te ontleed: ```json plutil -p /Library/Spotlight/iBooksAuthor.mdimporter/Contents/Info.plist [...] "CFBundleDocumentTypes" => [ - 0 => { - "CFBundleTypeName" => "iBooks Author Book" - "CFBundleTypeRole" => "MDImporter" - "LSItemContentTypes" => [ - 0 => "com.apple.ibooksauthor.book" - 1 => "com.apple.ibooksauthor.pkgbook" - 2 => "com.apple.ibooksauthor.template" - 3 => "com.apple.ibooksauthor.pkgtemplate" - ] - "LSTypeIsPackage" => 0 - } - ] +0 => { +"CFBundleTypeName" => "iBooks Author Book" +"CFBundleTypeRole" => "MDImporter" +"LSItemContentTypes" => [ +0 => "com.apple.ibooksauthor.book" +1 => "com.apple.ibooksauthor.pkgbook" +2 => "com.apple.ibooksauthor.template" +3 => "com.apple.ibooksauthor.pkgtemplate" +] +"LSTypeIsPackage" => 0 +} +] [...] - => { - "UTTypeConformsTo" => [ - 0 => "public.data" - 1 => "public.composite-content" - ] - "UTTypeDescription" => "iBooks Author Book" - "UTTypeIdentifier" => "com.apple.ibooksauthor.book" - "UTTypeReferenceURL" => "http://www.apple.com/ibooksauthor" - "UTTypeTagSpecification" => { - "public.filename-extension" => [ - 0 => "iba" - 1 => "book" - ] - } - } +=> { +"UTTypeConformsTo" => [ +0 => "public.data" +1 => "public.composite-content" +] +"UTTypeDescription" => "iBooks Author Book" +"UTTypeIdentifier" => "com.apple.ibooksauthor.book" +"UTTypeReferenceURL" => "http://www.apple.com/ibooksauthor" +"UTTypeTagSpecification" => { +"public.filename-extension" => [ +0 => "iba" +1 => "book" +] +} +} [...] ``` - > [!CAUTION] -> If you check the Plist of other `mdimporter` you might not find the entry **`UTTypeConformsTo`**.

The operation of MDM hinges on a compatible MDM server, which is either commercially available or open-source, and must support the [MDM Protocol](https://developer.apple.com/enterprise/documentation/MDM-Protocol-Reference.pdf). Key points include: +[Mobiele Toestelbestuur](https://en.wikipedia.org/wiki/Mobile_device_management) (MDM) word gebruik om verskeie eindgebruikertoestelle soos slimfone, skootrekenaars en tablette te bestuur. Veral vir Apple se platforms (iOS, macOS, tvOS), dit behels 'n stel gespesialiseerde funksies, API's en praktyke. Die werking van MDM hang af van 'n kompatible MDM-bediener, wat kommersieel beskikbaar of oopbron kan wees, en moet die [MDM-protokol](https://developer.apple.com/enterprise/documentation/MDM-Protocol-Reference.pdf) ondersteun. Sleutelpunte sluit in: -- Centralized control over devices. -- Dependence on an MDM server that adheres to the MDM protocol. -- Capability of the MDM server to dispatch various commands to devices, for instance, remote data erasure or configuration installation. +- Gekonsolideerde beheer oor toestelle. +- Afhangend van 'n MDM-bediener wat aan die MDM-protokol voldoen. +- Vermoë van die MDM-bediener om verskeie opdragte na toestelle te stuur, byvoorbeeld, afstandsdata-uitwissing of konfigurasie-installasie. -### **Basics of DEP (Device Enrollment Program)** +### **Basiese beginsels van DEP (Toestelregistrasieprogram)** -The [Device Enrollment Program](https://www.apple.com/business/site/docs/DEP_Guide.pdf) (DEP) offered by Apple streamlines the integration of Mobile Device Management (MDM) by facilitating zero-touch configuration for iOS, macOS, and tvOS devices. DEP automates the enrollment process, allowing devices to be operational right out of the box, with minimal user or administrative intervention. Essential aspects include: +Die [Toestelregistrasieprogram](https://www.apple.com/business/site/docs/DEP_Guide.pdf) (DEP) wat deur Apple aangebied word, stroomlyn die integrasie van Mobiele Toestelbestuur (MDM) deur nul-aanraakintegrasie vir iOS, macOS en tvOS toestelle te fasiliteer. DEP outomatiseer die registrasieproses, wat toestelle in staat stel om reg uit die boks te funksioneer, met minimale gebruikers- of administratiewe ingryping. Essensiële aspekte sluit in: -- Enables devices to autonomously register with a pre-defined MDM server upon initial activation. -- Primarily beneficial for brand-new devices, but also applicable for devices undergoing reconfiguration. -- Facilitates a straightforward setup, making devices ready for organizational use swiftly. +- Stel toestelle in staat om outonoom met 'n vooraf gedefinieerde MDM-bediener te registreer by die aanvanklike aktivering. +- Primêr voordelig vir splinternuwe toestelle, maar ook van toepassing op toestelle wat herkonfigureer word. +- Fasiliteer 'n eenvoudige opstelling, wat toestelle vinnig gereed maak vir organisatoriese gebruik. -### **Security Consideration** +### **Sekuriteitsoorweging** -It's crucial to note that the ease of enrollment provided by DEP, while beneficial, can also pose security risks. If protective measures are not adequately enforced for MDM enrollment, attackers might exploit this streamlined process to register their device on the organization's MDM server, masquerading as a corporate device. +Dit is belangrik om daarop te let dat die gemak van registrasie wat deur DEP verskaf word, terwyl dit voordelig is, ook sekuriteitsrisiko's kan inhou. As beskermingsmaatreëls nie voldoende afgedwing word vir MDM-registrasie nie, kan aanvallers hierdie gestroomlynde proses benut om hul toestel op die organisasie se MDM-bediener te registreer, terwyl hulle as 'n korporatiewe toestel voorgee. > [!CAUTION] -> **Security Alert**: Simplified DEP enrollment could potentially allow unauthorized device registration on the organization's MDM server if proper safeguards are not in place. +> **Sekuriteitswaarskuwing**: Vereenvoudigde DEP-registrasie kan moontlik ongeoorloofde toestelregistrasie op die organisasie se MDM-bediener toelaat as behoorlike beskermingsmaatreëls nie in plek is nie. -### Basics What is SCEP (Simple Certificate Enrolment Protocol)? +### Basiese beginsels Wat is SCEP (Eenvoudige Sertifikaatregistrasieprotokol)? -- A relatively old protocol, created before TLS and HTTPS were widespread. -- Gives clients a standardized way of sending a **Certificate Signing Request** (CSR) for the purpose of being granted a certificate.

Key components include: +Hierdie navorsing delf in die binaire lêers wat geassosieer word met die Toestel Registrasie Program (DEP) en Mobiele Toestel Bestuur (MDM) op macOS. Sleutelkomponente sluit in: -- **`mdmclient`**: Communicates with MDM servers and triggers DEP check-ins on macOS versions before 10.13.4. -- **`profiles`**: Manages Configuration Profiles, and triggers DEP check-ins on macOS versions 10.13.4 and later. -- **`cloudconfigurationd`**: Manages DEP API communications and retrieves Device Enrollment profiles. +- **`mdmclient`**: Kommunikeer met MDM-bedieners en aktiveer DEP-incheckings op macOS weergawes voor 10.13.4. +- **`profiles`**: Bestuur Konfigurasieprofiele, en aktiveer DEP-incheckings op macOS weergawes 10.13.4 en later. +- **`cloudconfigurationd`**: Bestuur DEP API kommunikasies en haal Toestel Registrasie profiele op. -DEP check-ins utilize the `CPFetchActivationRecord` and `CPGetActivationRecord` functions from the private Configuration Profiles framework to fetch the Activation Record, with `CPFetchActivationRecord` coordinating with `cloudconfigurationd` through XPC. +DEP-incheckings gebruik die `CPFetchActivationRecord` en `CPGetActivationRecord` funksies van die private Konfigurasieprofiele raamwerk om die Aktivering Rekord op te haal, met `CPFetchActivationRecord` wat saamwerk met `cloudconfigurationd` deur XPC. -## Tesla Protocol and Absinthe Scheme Reverse Engineering +## Tesla Protokol en Absinthe Skema Omgekeerde Ingenieurswese -The DEP check-in involves `cloudconfigurationd` sending an encrypted, signed JSON payload to _iprofiles.apple.com/macProfile_. The payload includes the device's serial number and the action "RequestProfileConfiguration". The encryption scheme used is referred to internally as "Absinthe". Unraveling this scheme is complex and involves numerous steps, which led to exploring alternative methods for inserting arbitrary serial numbers in the Activation Record request. +Die DEP-incheck betrek `cloudconfigurationd` wat 'n geënkripteerde, ondertekende JSON-payload na _iprofiles.apple.com/macProfile_ stuur. Die payload sluit die toestel se serienommer en die aksie "RequestProfileConfiguration" in. Die enkripsieskema wat gebruik word, word intern as "Absinthe" verwys. Om hierdie skema te ontrafel is kompleks en behels verskeie stappe, wat gelei het tot die verkenning van alternatiewe metodes om arbitrêre serienommers in die Aktivering Rekord versoek in te voeg. -## Proxying DEP Requests +## Proxie van DEP Versoeke -Attempts to intercept and modify DEP requests to _iprofiles.apple.com_ using tools like Charles Proxy were hindered by payload encryption and SSL/TLS security measures. However, enabling the `MCCloudConfigAcceptAnyHTTPSCertificate` configuration allows bypassing the server certificate validation, although the payload's encrypted nature still prevents modification of the serial number without the decryption key. +Pogings om DEP versoeke na _iprofiles.apple.com_ te onderskep en te wysig met behulp van gereedskap soos Charles Proxy is belemmer deur payload-enkripsie en SSL/TLS sekuriteitsmaatreëls. Dit is egter moontlik om die `MCCloudConfigAcceptAnyHTTPSCertificate` konfigurasie in te skakel, wat die bediener sertifikaat validasie omseil, alhoewel die geënkripteerde aard van die payload steeds die wysiging van die serienommer sonder die dekripsiesleutel verhinder. -## Instrumenting System Binaries Interacting with DEP +## Instrumentering van Stelsels Binaries wat met DEP Interaksie het -Instrumenting system binaries like `cloudconfigurationd` requires disabling System Integrity Protection (SIP) on macOS. With SIP disabled, tools like LLDB can be used to attach to system processes and potentially modify the serial number used in DEP API interactions. This method is preferable as it avoids the complexities of entitlements and code signing. +Instrumentering van stelsels binaries soos `cloudconfigurationd` vereis die deaktivering van Stelsel Integriteit Beskerming (SIP) op macOS. Met SIP gedeaktiveer, kan gereedskap soos LLDB gebruik word om aan stelsels prosesse te koppel en moontlik die serienommer wat in DEP API interaksies gebruik word, te wysig. Hierdie metode is verkieslik aangesien dit die kompleksiteite van regte en kode ondertekening vermy. -**Exploiting Binary Instrumentation:** -Modifying the DEP request payload before JSON serialization in `cloudconfigurationd` proved effective. The process involved: +**Eksploitering van Binaire Instrumentasie:** +Die wysiging van die DEP versoek payload voor JSON serialisering in `cloudconfigurationd` het effektief geblyk.

Injecting an arbitrary serial number into the memory before the payload is encrypted and sent. +1. Koppel LLDB aan `cloudconfigurationd`. +2.

The XNU kernel is part of the Darwin open source project, which means **its source code is freely accessible**. +Die **kern van macOS is XNU**, wat staan vir "X is Not Unix".

Most applications developed for BSD will compile and run on macOS without needing modifications, as the command-line tools familiar to Unix users are all present in macOS. However, because the XNU kernel incorporates Mach, there are some significant differences between a traditional Unix-like system and macOS, and these differences might cause potential issues or provide unique advantages. +Vanuit die perspektief van 'n sekuriteitsnavorsers of 'n Unix-ontwikkelaar, kan **macOS** baie **soortgelyk** voel aan 'n **FreeBSD** stelsel met 'n elegante GUI en 'n verskeidenheid van pasgemaakte toepassings. Meeste toepassings wat vir BSD ontwikkel is, sal saamgecompileer en op macOS loop sonder dat aanpassings nodig is, aangesien die opdraglyn gereedskap wat bekend is aan Unix-gebruikers, almal in macOS teenwoordig is. egter, omdat die XNU-kern Mach inkorporeer, is daar 'n paar beduidende verskille tussen 'n tradisionele Unix-agtige stelsel en macOS, en hierdie verskille kan potensiële probleme veroorsaak of unieke voordele bied. -Open source version of XNU: [https://opensource.apple.com/source/xnu/](https://opensource.apple.com/source/xnu/) +Open source weergawe van XNU: [https://opensource.apple.com/source/xnu/](https://opensource.apple.com/source/xnu/) ### Mach -Mach is a **microkernel** designed to be **UNIX-compatible**. One of its key design principles was to **minimize** the amount of **code** running in the **kernel** space and instead allow many typical kernel functions, such as file system, networking, and I/O, to **run as user-level tasks**. +Mach is 'n **mikrokerne**l wat ontwerp is om **UNIX-compatibel** te wees. Een van sy sleutelontwerp beginsels was om die hoeveelheid **kode** wat in die **kern** ruimte loop te **minimaliseer** en eerder toe te laat dat baie tipiese kern funksies, soos lêerstelsels, netwerk, en I/O, as **gebruikersvlak take** loop. -In XNU, Mach is **responsible for many of the critical low-level operations** a kernel typically handles, such as processor scheduling, multitasking, and virtual memory management. +In XNU is Mach **verantwoordelik vir baie van die kritieke laagvlak operasies** wat 'n kern tipies hanteer, soos prosessor skedulering, multitasking, en virtuele geheue bestuur. ### BSD -The XNU **kernel** also **incorporates** a significant amount of code derived from the **FreeBSD** project. This code **runs as part of the kernel along with Mach**, in the same address space. However, the FreeBSD code within XNU may differ substantially from the original FreeBSD code because modifications were required to ensure its compatibility with Mach. FreeBSD contributes to many kernel operations including: +Die XNU **kern** inkorporeer ook 'n beduidende hoeveelheid kode wat afkomstig is van die **FreeBSD** projek. Hierdie kode **loop as deel van die kern saam met Mach**, in dieselfde adresruimte. egter, die FreeBSD kode binne XNU mag aansienlik verskil van die oorspronklike FreeBSD kode omdat aanpassings nodig was om sy kompatibiliteit met Mach te verseker. FreeBSD dra by tot baie kern operasies insluitend: -- Process management -- Signal handling -- Basic security mechanisms, including user and group management -- System call infrastructure -- TCP/IP stack and sockets -- Firewall and packet filtering +- Proses bestuur +- Sein hantering +- Basiese sekuriteitsmeganismes, insluitend gebruiker en groep bestuur +- Stelselskakel infrastruktuur +- TCP/IP stapel en sokkies +- Vuurmuur en pakket filtrering -Understanding the interaction between BSD and Mach can be complex, due to their different conceptual frameworks. For instance, BSD uses processes as its fundamental executing unit, while Mach operates based on threads. This discrepancy is reconciled in XNU by **associating each BSD process with a Mach task** that contains exactly one Mach thread. When BSD's fork() system call is used, the BSD code within the kernel uses Mach functions to create a task and a thread structure. +Om die interaksie tussen BSD en Mach te verstaan, kan kompleks wees, as gevolg van hul verskillende konseptuele raamwerke. Byvoorbeeld, BSD gebruik prosesse as sy fundamentele uitvoerende eenheid, terwyl Mach werk op grond van drade. Hierdie verskil word in XNU versoen deur **elke BSD-proses te assosieer met 'n Mach-taak** wat presies een Mach-draad bevat. Wanneer BSD se fork() stelselskakel gebruik word, gebruik die BSD kode binne die kern Mach funksies om 'n taak en 'n draadstruktuur te skep. -Moreover, **Mach and BSD each maintain different security models**: **Mach's** security model is based on **port rights**, whereas BSD's security model operates based on **process ownership**. Disparities between these two models have occasionally resulted in local privilege-escalation vulnerabilities. Apart from typical system calls, there are also **Mach traps that allow user-space programs to interact with the kernel**. These different elements together form the multifaceted, hybrid architecture of the macOS kernel. +Boonop, **Mach en BSD handhaaf elk verskillende sekuriteitsmodelle**: **Mach se** sekuriteitsmodel is gebaseer op **poortregte**, terwyl BSD se sekuriteitsmodel werk op grond van **prosesbesit**. Verskille tussen hierdie twee modelle het af en toe gelei tot plaaslike voorreg-verhoging kwesbaarhede. Behalwe vir tipiese stelselskakels, is daar ook **Mach traps wat gebruikersvlak programme toelaat om met die kern te kommunikeer**. Hierdie verskillende elemente saam vorm die veelvlakkige, hibriede argitektuur van die macOS-kern. ### I/O Kit - Drivers -The I/O Kit is an open-source, object-oriented **device-driver framework** in the XNU kernel, handles **dynamically loaded device drivers**. It allows modular code to be added to the kernel on-the-fly, supporting diverse hardware. +Die I/O Kit is 'n open-source, objek-georiënteerde **toestel-bestuurder raamwerk** in die XNU-kern, wat **dynamies gelaaide toestel bestuurders** hanteer.

Hier is 'n paar van die algemene vliegtuie wat u in IORegistryExplorer mag teëkom: -1. **IOService Plane**: This is the most general plane, displaying the service objects that represent drivers and nubs (communication channels between drivers). It shows the provider-client relationships between these objects. -2. **IODeviceTree Plane**: This plane represents the physical connections between devices as they are attached to the system. It is often used to visualize the hierarchy of devices connected via buses like USB or PCI. -3. **IOPower Plane**: Displays objects and their relationships in terms of power management. It can show which objects are affecting the power state of others, useful for debugging power-related issues. -4. **IOUSB Plane**: Specifically focused on USB devices and their relationships, showing the hierarchy of USB hubs and connected devices. -5. **IOAudio Plane**: This plane is for representing audio devices and their relationships within the system. +1. **IOService Plane**: Dit is die mees algemene vliegtuig, wat die diensobjekte vertoon wat stuurprogramme en nubs (kommunikasiekanale tussen stuurprogramme) verteenwoordig. Dit toon die verskaffer-klant verhoudings tussen hierdie objek. +2. **IODeviceTree Plane**: Hierdie vliegtuig verteenwoordig die fisiese verbande tussen toestelle soos hulle aan die stelsel gekoppel is. Dit word dikwels gebruik om die hiërargie van toestelle wat via busse soos USB of PCI gekoppel is, te visualiseer. +3. **IOPower Plane**: Vertoon objek en hul verhoudings in terme van kragbestuur. Dit kan wys watter objek die kragtoestand van ander beïnvloed, nuttig vir die ontfouting van kragverwante probleme. +4. **IOUSB Plane**: Spesifiek gefokus op USB-toestelle en hul verhoudings, wat die hiërargie van USB-hubs en gekonnekteerde toestelle toon. +5. **IOAudio Plane**: Hierdie vliegtuig is vir die verteenwoordiging van klanktoestelle en hul verhoudings binne die stelsel. 6. ... ## Driver Comm Code Example -The following code connects to the IOKit service `"YourServiceNameHere"` and calls the function inside the selector 0.

Mach ports are MPSC (multiple-producer, single-consumer) queues, which means that there may only ever be **one receive right for each port** in the whole system (unlike with pipes, where multiple processes can all hold file descriptors to the read end of one pipe). - - A **task with the Receive** right can receive messages and **create Send rights**, allowing it to send messages.

Dequeuing a message from a port set dequeues a message from one of the ports it contains. Port sets can be used to listen on several ports simultaneously, a lot like `select`/`poll`/`epoll`/`kqueue` in Unix. -- **Dead name**, which is not an actual port right, but merely a placeholder. When a port is destroyed, all existing port rights to the port turn into dead names. +- **Ontvang reg**, wat die ontvangs van boodskappe wat na die poort gestuur word, toelaat. Mach poorte is MPSC (meervoudige produsent, enkele verbruiker) rye, wat beteken dat daar slegs **een ontvang reg vir elke poort** in die hele stelsel mag wees (in teenstelling met pype, waar verskeie prosesse almal lêer beskrywings na die leeskant van een pyp kan hou). +- 'n **taak met die Ontvang** reg kan boodskappe ontvang en **Stuur regte** skep, wat dit toelaat om boodskappe te stuur.

Om 'n boodskap van 'n poort stel te verwyder, verwyder 'n boodskap van een van die poorte wat dit bevat. Poort stelle kan gebruik word om op verskeie poorte gelyktydig te luister, baie soos `select`/`poll`/`epoll`/`kqueue` in Unix. +- **Dood naam**, wat nie 'n werklike poort reg is nie, maar bloot 'n plekhouer. Wanneer 'n poort vernietig word, draai al bestaande poort regte na die poort in dood name. -**Tasks can transfer SEND rights to others**, enabling them to send messages back. **SEND rights can also be cloned, so a task can duplicate and give the right to a third task**.

Task **A** initiates a **new port**, obtaining a **RECEIVE right** in the process. -2. Task **A**, being the holder of the RECEIVE right, **generates a SEND right for the port**. -3. Task **A** establishes a **connection** with the **bootstrap server**, providing the **port's service name** and the **SEND right** through a procedure known as the bootstrap register. -4. Task **B** interacts with the **bootstrap server** to execute a bootstrap **lookup for the service** name. If successful, the **server duplicates the SEND right** received from Task A and **transmits it to Task B**. -5. Upon acquiring a SEND right, Task **B** is capable of **formulating** a **message** and dispatching it **to Task A**. -6. For a bi-directional communication usually task **B** generates a new port with a **RECEIVE** right and a **SEND** right, and gives the **SEND right to Task A** so it can send messages to TASK B (bi-directional communication). +1. Taak **A** begin 'n **nuwe poort**, en verkry 'n **ONTVAAG reg** in die proses. +2. Taak **A**, as die houer van die ONTVANG reg, **genereer 'n STUUR reg vir die poort**. +3. Taak **A** vestig 'n **verbinding** met die **bootstrap bediener**, en bied die **poort se diensnaam** en die **STUUR reg** deur 'n prosedure bekend as die bootstrap registrasie. +4. Taak **B** interaksie met die **bootstrap bediener** om 'n bootstrap **soektog vir die diens** naam uit te voer. As dit suksesvol is, **dupliseer die bediener die STUUR reg** wat van Taak A ontvang is en **stuur dit na Taak B**. +5. Na die verkryging van 'n STUUR reg, is Taak **B** in staat om 'n **boodskap** te **formuleer** en dit **na Taak A** te stuur. +6. Vir 'n bi-rigting kommunikasie genereer taak **B** gewoonlik 'n nuwe poort met 'n **ONTVAAG** reg en 'n **STUUR** reg, en gee die **STUUR reg aan Taak A** sodat dit boodskappe na TAak B kan stuur (bi-rigting kommunikasie). -The bootstrap server **cannot authenticate** the service name claimed by a task. This means a **task** could potentially **impersonate any system task**, such as falsely **claiming an authorization service name** and then approving every request. +Die bootstrap bediener **kan nie die diensnaam wat deur 'n taak geclaim word, verifieer nie**. Dit beteken 'n **taak** kan potensieel **enige stelseltaak naboots**, soos valslik **'n magtiging diensnaam te claim** en dan elke versoek goedkeur. -Then, Apple stores the **names of system-provided services** in secure configuration files, located in **SIP-protected** directories: `/System/Library/LaunchDaemons` and `/System/Library/LaunchAgents`. Alongside each service name, the **associated binary is also stored**. The bootstrap server, will create and hold a **RECEIVE right for each of these service names**. +Dan, Apple stoor die **name van stelsel-geleverde dienste** in veilige konfigurasie lêers, geleë in **SIP-beskermde** gidse: `/System/Library/LaunchDaemons` en `/System/Library/LaunchAgents`. Saam met elke diensnaam, word die **geassosieerde binêre ook gestoor**. Die bootstrap bediener sal 'n **ONTVAAG reg vir elkeen van hierdie diensname** skep en hou. -For these predefined services, the **lookup process differs slightly**. When a service name is being looked up, launchd starts the service dynamically. The new workflow is as follows: +Vir hierdie vooraf gedefinieerde dienste, verskil die **soekproses effens**. Wanneer 'n diensnaam gesoek word, begin launchd die diens dinamies. Die nuwe werksvloei is soos volg: -- Task **B** initiates a bootstrap **lookup** for a service name. -- **launchd** checks if the task is running and if it isn’t, **starts** it. -- Task **A** (the service) performs a **bootstrap check-in**. Here, the **bootstrap** server creates a SEND right, retains it, and **transfers the RECEIVE right to Task A**. -- launchd duplicates the **SEND right and sends it to Task B**. -- Task **B** generates a new port with a **RECEIVE** right and a **SEND** right, and gives the **SEND right to Task A** (the svc) so it can send messages to TASK B (bi-directional communication). +- Taak **B** begin 'n bootstrap **soektog** vir 'n diensnaam. +- **launchd** kyk of die taak loop en as dit nie is nie, **begin** dit. +- Taak **A** (die diens) voer 'n **bootstrap incheck** uit. Hier, die **bootstrap** bediener skep 'n STUUR reg, hou dit, en **oordra die ONTVANG reg aan Taak A**. +- launchd dupliseer die **STUUR reg en stuur dit na Taak B**. +- Taak **B** genereer 'n nuwe poort met 'n **ONTVAAG** reg en 'n **STUUR** reg, en gee die **STUUR reg aan Taak A** (die svc) sodat dit boodskappe na TAak B kan stuur (bi-rigting kommunikasie). -However, this process only applies to predefined system tasks. Non-system tasks still operate as described originally, which could potentially allow for impersonation. +Hierdie proses geld egter slegs vir vooraf gedefinieerde stelseltaake. Nie-stelseltaake werk steeds soos oorspronklik beskryf, wat potensieel nabootsing kan toelaat. -### A Mach Message +### 'n Mach Boodskap -[Find more info here](https://sector7.computest.nl/post/2023-10-xpc-audit-token-spoofing/) - -The `mach_msg` function, essentially a system call, is utilized for sending and receiving Mach messages.

Conversely, the **senders** are granted a _**send**_ or a _**send-once right**_.

The only thing that seems to be available through it is `task_info()`. -- **Task port** (aka kernel port)**:** With Send permission over this port it's possible to control the task (read/write memory, create threads...). - - Call `mach_task_self()` to **get the name** for this port for the caller task. This port is only **inherited** across **`exec()`**; a new task created with `fork()` gets a new task port (as a special case, a task also gets a new task port after `exec()`in a suid binary).

The thread we generated in the previous injection, was generated using Mach api, so **it's not posix compliant**. +Dit was moontlik om **'n eenvoudige shellcode** in te spuit om 'n opdrag uit te voer omdat dit **nie met posix** konforme apis hoef te werk nie, net met Mach. **Meer komplekse inspuitings** sou vereis dat die **draad** ook **posix-konform** moet wees. -It was possible to **inject a simple shellcode** to execute a command because it **didn't need to work with posix** compliant apis, only with Mach. **More complex injections** would need the **thread** to be also **posix compliant**. +Daarom, om die **draad** te **verbeter**, moet dit **`pthread_create_from_mach_thread`** aanroep wat **'n geldige pthread** sal skep. Dan kan hierdie nuwe pthread **dlopen** aanroep om **'n dylib** van die stelsel te laai, sodat dit in plaas daarvan om nuwe shellcode te skryf om verskillende aksies uit te voer, moontlik is om pasgemaakte biblioteke te laai. -Therefore, to **improve the thread** it should call **`pthread_create_from_mach_thread`** which will **create a valid pthread**. Then, this new pthread could **call dlopen** to **load a dylib** from the system, so instead of writing new shellcode to perform different actions it's possible to load custom libraries. - -You can find **example dylibs** in (for example the one that generates a log and then you can listen to it): +Jy kan **voorbeeld dylibs** vind in (byvoorbeeld die een wat 'n log genereer en dan kan jy daarna luister): {{#ref}} ../../macos-dyld-hijacking-and-dyld_insert_libraries.md @@ -531,7 +515,6 @@ You can find **example dylibs** in (for example the one that generates a log and

This KEXT is made up of several key components: +Die kern van hierdie raamwerk is in die kern geïmplementeer, as 'n Kern Uitbreiding (KEXT) geleë by **`/System/Library/Extensions/EndpointSecurity.kext`**. Hierdie KEXT bestaan uit verskeie sleutelkomponente: -- **EndpointSecurityDriver**: This acts as the "entry point" for the kernel extension. It's the main point of interaction between the OS and the Endpoint Security framework. -- **EndpointSecurityEventManager**: This component is responsible for implementing kernel hooks. Kernel hooks allow the framework to monitor system events by intercepting system calls. -- **EndpointSecurityClientManager**: This manages the communication with user space clients, keeping track of which clients are connected and need to receive event notifications. -- **EndpointSecurityMessageManager**: This sends messages and event notifications to user space clients. +- **EndpointSecurityDriver**: Dit dien as die "toegangspunt" vir die kernuitbreiding. Dit is die hoofpunt van interaksie tussen die OS en die Eindpunt Sekuriteit raamwerk. +- **EndpointSecurityEventManager**: Hierdie komponent is verantwoordelik vir die implementering van kernhake. Kernhake laat die raamwerk toe om stelselsgebeurtenisse te monitor deur stelselsoproepe te onderskep. +- **EndpointSecurityClientManager**: Dit bestuur die kommunikasie met gebruikersruimte kliënte, en hou dop watter kliënte verbind is en gebeurteniskennisgewings moet ontvang. +- **EndpointSecurityMessageManager**: Dit stuur boodskappe en gebeurteniskennisgewings na gebruikersruimte kliënte. -The events that the Endpoint Security framework can monitor are categorized into: +Die gebeurtenisse wat die Eindpunt Sekuriteit raamwerk kan monitor, is gekategoriseer in: -- File events -- Process events -- Socket events -- Kernel events (such as loading/unloading a kernel extension or opening an I/O Kit device) +- Lêergebeurtenisse +- Prosesgebeurtenisse +- Sokketgebeurtenisse +- Kerngebeurtenisse (soos die laai/ontlaai van 'n kernuitbreiding of die opening van 'n I/O Kit toestel) -### Endpoint Security Framework Architecture +### Eindpunt Sekuriteit Raamwerk Argitektuur

-**User-space communication** with the Endpoint Security framework happens through the IOUserClient class. Two different subclasses are used, depending on the type of caller: +**Gebruikersruimte kommunikasie** met die Eindpunt Sekuriteit raamwerk gebeur deur die IOUserClient klas. Twee verskillende subklasse word gebruik, afhangende van die tipe oproeper: -- **EndpointSecurityDriverClient**: This requires the `com.apple.private.endpoint-security.manager` entitlement, which is only held by the system process `endpointsecurityd`. -- **EndpointSecurityExternalClient**: This requires the `com.apple.developer.endpoint-security.client` entitlement. This would typically be used by third-party security software that needs to interact with the Endpoint Security framework. +- **EndpointSecurityDriverClient**: Dit vereis die `com.apple.private.endpoint-security.manager` regte, wat slegs deur die stelselsproses `endpointsecurityd` besit word. +- **EndpointSecurityExternalClient**: Dit vereis die `com.apple.developer.endpoint-security.client` regte.

It's a technology developed by Apple to optimize application support for concurrent (multithreaded) execution on multicore hardware. +**Grand Central Dispatch (GCD),** ook bekend as **libdispatch** (`libdispatch.dyld`), is beskikbaar in beide macOS en iOS. Dit is 'n tegnologie wat deur Apple ontwikkel is om toepassingsondersteuning vir gelyktydige (multithreaded) uitvoering op veelkern-hardware te optimaliseer. -**GCD** provides and manages **FIFO queues** to which your application can **submit tasks** in the form of **block objects**. Blocks submitted to dispatch queues are **executed on a pool of threads** fully managed by the system. GCD automatically creates threads for executing the tasks in the dispatch queues and schedules those tasks to run on the available cores. +**GCD** bied en bestuur **FIFO-rye** waaraan jou toepassing **take** in die vorm van **blokobjekte** kan **indien**. Blokke wat aan afleweringsrye ingedien word, word **uitgevoer op 'n poel van drade** wat volledig deur die stelsel bestuur word. GCD skep outomaties drade om die take in die afleweringsrye uit te voer en skeduleer daardie take om op die beskikbare kerne te loop. > [!TIP] -> In summary, to execute code in **parallel**, processes can send **blocks of code to GCD**, which will take care of their execution. Therefore, processes don't create new threads; **GCD executes the given code with its own pool of threads** (which might increase or decrease as necessary). +> In samevatting, om kode in **parallel** uit te voer, kan prosesse **blokke van kode na GCD** stuur, wat sorg vir hul uitvoering. Daarom skep prosesse nie nuwe drade nie; **GCD voer die gegewe kode uit met sy eie poel van drade** (wat kan toeneem of afneem soos nodig). -This is very helpful to manage parallel execution successfully, greatly reducing the number of threads processes create and optimising the parallel execution. This is ideal for tasks that require **great parallelism** (brute-forcing?) or for tasks that shouldn't block the main thread: For example, the main thread on iOS handles UI interactions, so any other functionality that could make the app hang (searching, accessing a web, reading a file...) is managed this way. +Dit is baie nuttig om parallelle uitvoering suksesvol te bestuur, wat die aantal drade wat prosesse skep, aansienlik verminder en die parallelle uitvoering optimaliseer. Dit is ideaal vir take wat **groot parallelisme** vereis (brute-forcing?) of vir take wat nie die hoofdraad moet blokkeer nie: Byvoorbeeld, die hoofdraad op iOS hanteer UI-interaksies, so enige ander funksionaliteit wat die toepassing kan laat hang (soek, toegang tot 'n web, lees 'n lêer...) word op hierdie manier bestuur. -### Blocks +### Blokke -A block is a **self contained section of code** (like a function with arguments returning a value) and can also specify bound variables.\ -However, at compiler level blocks doesn't exist, they are `os_object`s.

But **the other type of queue might have it**. +Blokke word in rye gestel om uitgevoer te word, en hierdie ondersteun 2 modi: `DISPATCH_QUEUE_SERIAL` en `DISPATCH_QUEUE_CONCURRENT`.

Ook bekend as Rendezvous, **Zero Configuration**, of Zeroconf, stel dit 'n toestel in staat om by 'n TCP/IP-netwerk aan te sluit, **automaties 'n IP-adres te kies**, en sy dienste aan ander netwerktoestelle te broadcast. -Bonjour, an Apple-designed technology, allows **devices on the same network to detect each other's offered services**. Known also as Rendezvous, **Zero Configuration**, or Zeroconf, it enables a device to join a TCP/IP network, **automatically choose an IP address**, and broadcast its services to other network devices. +Zero Configuration Networking, wat deur Bonjour verskaf word, verseker dat toestelle kan: -Zero Configuration Networking, provided by Bonjour, ensures that devices can: +- **Automaties 'n IP-adres verkry** selfs in die afwesigheid van 'n DHCP-bediener. +- **Naam-naar-adres vertaling** uitvoer sonder om 'n DNS-bediener te vereis. +- **Dienste** beskikbaar op die netwerk ontdek. -- **Automatically obtain an IP Address** even in the absence of a DHCP server. -- Perform **name-to-address translation** without requiring a DNS server. -- **Discover services** available on the network. +Toestelle wat Bonjour gebruik, sal vir hulleself 'n **IP-adres uit die 169.254/16 reeks toewys** en die uniekheid daarvan op die netwerk verifieer. Macs hou 'n routeringstabelinvoer vir hierdie subnet, wat verifieer kan word via `netstat -rn | grep 169`. -Devices using Bonjour will assign themselves an **IP address from the 169.254/16 range** and verify its uniqueness on the network. Macs maintain a routing table entry for this subnet, verifiable via `netstat -rn | grep 169`. +Vir DNS gebruik Bonjour die **Multicast DNS (mDNS) protokol**. mDNS werk oor **poort 5353/UDP**, wat **standaard DNS-vrae** gebruik maar teiken die **multicast adres 224.0.0.251**. Hierdie benadering verseker dat alle luisterende toestelle op die netwerk die vrae kan ontvang en daarop kan reageer, wat die opdatering van hul rekords fasiliteer. -For DNS, Bonjour utilizes the **Multicast DNS (mDNS) protocol**. mDNS operates over **port 5353/UDP**, employing **standard DNS queries** but targeting the **multicast address 224.0.0.251**. This approach ensures that all listening devices on the network can receive and respond to the queries, facilitating the update of their records. +By die aansluiting by die netwerk, kies elke toestel self 'n naam, wat tipies eindig op **.local**, wat afgelei kan wees van die gasheernaam of ewekansig gegenereer kan word. -Upon joining the network, each device self-selects a name, typically ending in **.local**, which may be derived from the hostname or randomly generated. +Dienste ontdekking binne die netwerk word gefasiliteer deur **DNS Service Discovery (DNS-SD)**. Deur die formaat van DNS SRV rekords te benut, gebruik DNS-SD **DNS PTR rekords** om die lys van verskeie dienste moontlik te maak. 'n Kliënt wat 'n spesifieke diens soek, sal 'n PTR rekord vir `.` aan vra, en in ruil 'n lys van PTR rekords ontvang wat geformateer is as `..` indien die diens beskikbaar is vanaf verskeie gasheers. -Service discovery within the network is facilitated by **DNS Service Discovery (DNS-SD)**. Leveraging the format of DNS SRV records, DNS-SD uses **DNS PTR records** to enable the listing of multiple services. A client seeking a specific service will request a PTR record for `.`, receiving in return a list of PTR records formatted as `..` if the service is available from multiple hosts. +Die `dns-sd` nut kan gebruik word vir **die ontdekking en advertering van netwerkdienste**. Hier is 'n paar voorbeelde van sy gebruik: -The `dns-sd` utility can be employed for **discovering and advertising network services**. Here are some examples of its usage: - -### Searching for SSH Services - -To search for SSH services on the network, the following command is used: +### Soek na SSH Dienste +Om na SSH dienste op die netwerk te soek, word die volgende opdrag gebruik: ```bash dns-sd -B _ssh._tcp ``` +Hierdie opdrag begin om te soek na \_ssh.\_tcp dienste en gee besonderhede soos tydstempel, vlae, koppelvlak, domein, dienste tipe, en instansie naam. -This command initiates browsing for \_ssh.\_tcp services and outputs details such as timestamp, flags, interface, domain, service type, and instance name. - -### Advertising an HTTP Service - -To advertise an HTTP service, you can use: +### Advertering van 'n HTTP Diens +Om 'n HTTP diens te adverteer, kan jy gebruik maak van: ```bash dns-sd -R "Index" _http._tcp . 80 path=/index.html ``` +Hierdie opdrag registreer 'n HTTP-diens genaamd "Index" op poort 80 met 'n pad van `/index.html`. -This command registers an HTTP service named "Index" on port 80 with a path of `/index.html`. - -To then search for HTTP services on the network: - +Om dan vir HTTP-dienste op die netwerk te soek: ```bash dns-sd -B _http._tcp ``` +Wanneer 'n diens begin, kondig dit sy beskikbaarheid aan alle toestelle op die subnet aan deur sy teenwoordigheid te multicast. Toestelle wat in hierdie dienste belangstel, hoef nie versoeke te stuur nie, maar luister eenvoudig na hierdie aankondigings. -When a service starts, it announces its availability to all devices on the subnet by multicasting its presence. Devices interested in these services don't need to send requests but simply listen for these announcements. - -For a more user-friendly interface, the **Discovery - DNS-SD Browser** app available on the Apple App Store can visualize the services offered on your local network. - -Alternatively, custom scripts can be written to browse and discover services using the `python-zeroconf` library. The [**python-zeroconf**](https://github.com/jstasiak/python-zeroconf) script demonstrates creating a service browser for `_http._tcp.local.` services, printing added or removed services: +Vir 'n meer gebruikersvriendelike koppelvlak kan die **Discovery - DNS-SD Browser** app beskikbaar op die Apple App Store die dienste wat op jou plaaslike netwerk aangebied word, visualiseer. +Alternatiewelik kan pasgemaakte skripte geskryf word om dienste te blaai en te ontdek met behulp van die `python-zeroconf` biblioteek.
