- **Dec 2025**: Added detection for sudo configurations that expose restic's `--password-command` helper, a common privilege escalation vector observed in real environments.

It uses **/bin/sh** syntax, so can run in anything supporting `sh` (and the binaries and parameters used).

# Title: System Information - CVE_2025_38236
|

# ID: SY_CVE_2025_38236

# Author: HT Bot

# Last Update: 17-12-2025
|
||||
# Description: Detect Linux kernels exposed to CVE-2025-38236 (AF_UNIX MSG_OOB UAF) that allow local privilege escalation:
|
||||
# - Vulnerable scope:
|
||||
# * Linux kernels 6.9+ before commit 32ca245464e1479bfea8592b9db227fdc1641705
|
||||
# * AF_UNIX stream sockets with MSG_OOB enabled (CONFIG_AF_UNIX_OOB or implicit support)
|
||||
# - Exploitation summary:
|
||||
# * send/recv MSG_OOB pattern leaves zero-length SKBs in the receive queue
|
||||
# * manage_oob() skips cleanup, freeing the OOB SKB while u->oob_skb still points to it
|
||||
# * Subsequent recv(MSG_OOB) dereferences the dangling pointer → kernel UAF → LPE
|
||||
# - Mitigations:
|
||||
# * Update to a kernel that includes commit 32ca245464e1479bfea8592b9db227fdc1641705 (or newer)
|
||||
# * Disable CONFIG_AF_UNIX_OOB or block MSG_OOB in sandboxed processes
|
||||
# * Backport vendor fixes or follow Chrome's MSG_OOB filtering approach

# Description: Detect Linux kernels that may still be vulnerable to CVE-2025-38352 (race-condition UAF in POSIX CPU timers)
|

# - Highlights kernels built without CONFIG_POSIX_CPU_TIMERS_TASK_WORK
|
||||
# - Flags 6.12.x builds older than the fix commit f90fff1e152dedf52b932240ebbd670d83330eca (first shipped in 6.12.34)
|
||||
# - Provides quick risk scoring so operators can decide whether to attempt the publicly available PoC
|
||||
# - Core requirements for exploitation:
|
||||
# * CONFIG_POSIX_CPU_TIMERS_TASK_WORK disabled (common on 32-bit Android / custom kernels)
|
||||
# * Lack of the upstream exit_state guard in run_posix_cpu_timers()

|

|
||||
The goal of this project is to search for possible **Privilege Escalation Paths** in Windows environments.
|
||||
|
||||
New in this version:
|
||||
- Detect potential GPO abuse by flagging writable SYSVOL paths for GPOs applied to the current host and by highlighting membership in the "Group Policy Creator Owners" group.
|
||||
- Highlight HKLM/HKU registry keys that grant write access to low-privileged groups (including the cross-user TypingInsights key) so you can spot the hive corruption primitives documented by Project Zero.
|
||||
|
||||
|
||||
It should take only a **few seconds** to execute almost all the checks and **some seconds/minutes during the lasts checks searching for known filenames** that could contain passwords (the time depened on the number of files in your home folder). By default only **some** filenames that could contain credentials are searched, you can use the **searchall** parameter to search all the list (this could will add some minutes).
|
||||
|
||||
The tool is based on **[SeatBelt](https://github.com/GhostPack/Seatbelt)**.
|
||||
|
||||
### New (AD-aware) checks
|
||||
|
||||
- Active Directory quick checks now include:
|
||||
- gMSA readable managed passwords: enumerate msDS-GroupManagedServiceAccount objects and report those where the current user/group is allowed to retrieve the managed password (PrincipalsAllowedToRetrieveManagedPassword).
|
||||
- AD CS (ESC4) hygiene: enumerate published certificate templates and highlight templates where the current user/group has dangerous control rights (GenericAll/WriteDacl/WriteOwner/WriteProperty/ExtendedRight) that could allow template abuse (e.g., ESC4 -> ESC1).
|
||||
|
||||
These checks are lightweight, read-only, and only run when the host is domain-joined.
