Level 20


  1. SSH to bandit19
  2. Use the SUID binary in the homedirectory to get the password from /etc/bandit_pass

Objective 1

  • Username: bandit19
  • Password: IueksS7Ubh8G3DCwVzrTd8rAVOwq3M5x
  • Port: 2220
  • IP/Hostname: bandit.labs.overthewire.org
user@localhost:~$ ssh -p 2220 [email protected]


Objective 2

We need to find out how to use the binary.

They tell us to run the binary without arguments to learn what it does.

bandit19@bandit:~$ ./bandit20-do 
Run a command as another user.
  Example: ./bandit20-do id

So all we need to do is run the binary (which should run as bandit20) to try to read /etc/bandit_pass/bandit20.

bandit19@bandit:~$ ./bandit20-do cat /etc/bandit_pass/bandit20
