Bandit Level 20

Level Goal There is a setuid binary in the homedirectory that does the following: it makes a connection to localhost on the port you specify as a commandline argument. It then reads a line of text from the connection and compares it to the password in the previous level (bandit20). If the password is correct, it will transmit the password for the next level (bandit21).

NOTE

Try connecting to your own network daemon to see if it works as you think

Commands you may need to solve this level ssh, nc, cat, bash, screen, tmux, Unix ‘job control’ (bg, fg, jobs, &, CTRL-Z, …)

SSH

ssh bandit20@bandit.labs.overthewire.org -p 2220
