Introduction
Greetings, Welcome back to the OverTheWire Bandit challenges. In this level, we are presented with a custom binary that has to be exploited to get secret information.
Previous Flag
In the previous challenge, we successfully acquired the following flag:

Exploring bandit20-do
Our next task involves the execution of the ./bandit20-do
command. Let's initiate it and see what it does:
./bandit20-do
It seems like this binary executes whatever bash command we provide as the user we want to escalate to, bandit20.
Retrieving Bandit20 Password
Now that we have access to bandit20-do
, let's utilize it to read the contents of the /etc/bandit_pass/bandit20
file:
./bandit20-do cat /etc/bandit_pass/bandit20
Executing this command should reveal the password for the Bandit level 20.
