CSAW 2014 walkthrough – pybabbies

pybabbies was an Exploitation 200 challenge during the CTF and I got “voluntold” to work on this one by my team mates since I have a strong Python background. The night was young and I felt pretty good about it, so I took a look.

Setting the scene

Connecting to that IP/port with netcat revealed a shell prompt indicating that I had connected to a Python sandbox environment. Python sandboxes are nothing new, and I had actually recently done some reading on a sandbox challenge from an older CTF writeup so I felt pretty good about what I was getting myself in to.
