Uptux : Linux Privilege Escalation Checks

Uptux is a specialized privilege escalation checks for Linux systems. Implemented so far:

  • Writable systemd paths, services, timers, and socket units
  • Disassembles systemd unit files looking for:
    • References to executables that are writable
    • References to broken symlinks pointing to writeable directories
    • Relative path statements
    • Unix socket files that are writeable (sneaky APIs)
  • Writable D-Bus paths
  • Overly permissive D-Bus service settings
  • HTTP APIs running as root and responding on file-bound unix domain sockets

These checks are based on things I encounter during my own research, and this tool is certainly not inclusive of everything you should be looking at. Don’t skip the classics!

Usage

All functionality is contained in a single file, because installing packages in restricted shells is a pain. Python2 compatibility will be maintained for those crap old boxes we get stuck with. However, as the checks are really aimed at more modern user-space stuff, it is unlikely to uncover anything interesting on an old box anyway.

There is nothing to install, just grab the script and run it.

usage: uptux.py [-h] [-n] [-d]

PrivEsc for modern Linux systems, by initstring (github.com/initstring)

optional arguments:
-h, –help show this help message and exit
-n, –nologging do not write the output to a logfile
-d, –debug print some extra debugging info to the console

Testing

For testing purposes, you can run the tests/r00tme.sh script, which will create many vulnerable configuration issues on your system that uptux can identify. Running tests/unr00tme.sh will undo these changes, but don’t hold me to it. Needless to say, this is dangerous.

Use a VM for testing this way.
