PrivilegeEscalation

Hello, this is my write up of the Prison Escape challenge for kringlecon 2022. The aim of this challenge is to escape a container aka a container breakout. I must admit I did run down a rabbit hole when doing my first attempt but once I realised the answer it became quite obvious. Below here we have the starting terminal which you see when starting the challenge. Typically the first thing I do when I have a shell whether it be a vm or container is check whether I have sudo privileges, most often than not low privilege users are given more sudo privileges than they actually need, this creates a security risk and path for an attacker to escalate to root.
