## [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 :)
