- ## [Title]: linuxprivchecker.py -- a Linux Privilege Escalation Check Script
- ## [Author]: Mike Czumak (T_v3rn1x) -- @SecuritySift
- ##-------------------------------------------------------------------------------------------------------------
- ## [Details]:
- ## This script is intended to be executed locally on a Linux box to enumerate basic system info and
- ## search for common privilege escalation vectors such as world writable files, misconfigurations, clear-text
- ## passwords and applicable exploits.
- ##-------------------------------------------------------------------------------------------------------------
- ## [Warning]:
- ## This script comes as-is with no promise of functionality or accuracy. I have no plans to maintain updates,
- ## I did not write it to be efficient and in some cases you may find the functions may not produce the desired
- ## results. For example, the function that links packages to running processes is based on keywords and will
- ## not always be accurate. Also, the exploit list included in this function will need to be updated over time.
- ## Feel free to change or improve it any way you see fit.
- ##-------------------------------------------------------------------------------------------------------------
- ## [Modification, Distribution, and Attribution]:
- ## You are free to modify and/or distribute this script as you wish. I only ask that you maintain original
- ## author attribution and not attempt to sell it or incorporate it into any commercial offering (as if it's
- ## worth anything anyway :)
