Level 18

Login

SSH: ssh [email protected] -p 2220

Challenge URL: https://overthewire.org/wargames/bandit/bandit19.html

Task

The password for the next level is stored in a file readme in the home directory. Unfortunately, someone has modified .bashrc to log you out when you log in with SSH.

Solution

After logging in, the .bashrc file automatically logs you out instantly - so pass the command in quotes after the SSH query to execute commands before it logs you out.
First send ls and we see readme file is present, so just cat the readme file.

bob@laptop:~/documents$ ssh bandit.labs.overthewire.org -p 2220 -l bandit18 "ls";
 
-- SNIP
 
[email protected]'s password:
readme

One liner: ssh bandit.labs.overthewire.org -p 2220 -l bandit18 "cat readme";
