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
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)
-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
For testing purposes, you can run the
tests/r00tme.shscript, which will create many vulnerable configuration issues on your system that uptux can identify. Running
tests/unr00tme.shwill undo these changes, but don't hold me to it. Needless to say, this is dangerous.
Use a VM for testing this way.
