RCE for old gitlab version <= 11.4.7 & 12.4.0-12.8.1

LFI for old gitlab versions 10.4 - 12.8.1

This is an exploit for old Gitlab versions. This shouldnt work in the wild but it still seems to be popular in CTFs. Educational use only. Illegal things are illegal.

CVEs: CVE-2018-19571 (SSRF) + CVE-2018-19585 (CRLF) & CVE-2020-10977

partly inspired by the gitlab RCE metasploit module

usage:

python gitlab_rce.py <http://gitlab:port> <local-ip>

You might or might not have to tweak this a bit.

THERE ARE ABSOLUTELY !!NO!! VERY A FEW CHECKS OR ERROR HANDLING!

needs a HUGE refactor some time in the future.
