Editor from HackTheBox is an easy level Linux CTF all about program enumeration and public exploits. The foothold involves enumerating a webserver on a non-default port that is running a vulnerable version of XWiki that allows us to get remote code execution. From there we can look around on the box until we find a config file containing a cleartext password that is shared with the oliver user account on the box. Once we have access to the oliver account, we will discover that our group permissions grant us the ability to run ndsudo as the root user. The version of ndsudo has a privilege escalation vulnerability that will allow us to spawn a shell as root and own the box.
