GTFONow - Automatic privilege escalation for misconfigured c

项目说明

![Main Branch]()

GTFONow

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

![asciicast]()

✅ 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 | python

💻 Usage

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

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

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 aggressi 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 interacti. This is mainly for debugging purposes.

- Example: python gtfonow.py --command 'ls -la'

--auto: Automatically exploits without user wizard.

-v, --: Enables output.

- Example: python gtfonow.py --

Compatibility

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

Python2.\*

Python3.\*

No 3rd party dependencies

Any Unix (Linux, MacOS,\*Nix)

Any architecture eg (X86/ARM64/X86-64)
