##-------------------------------------------------------------------------------------------------------------
## [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.
