OSCP Practice with Proving Grounds - DriftingBlue6

In this video, we take on DriftingBlue6 from OffSec Proving Grounds Practice in preparation for the OSCP exam. Now, this was an easy level box that rewards for good enumeration and situational awareness. We end up enumerating a web application that allows us to find a zip file. We then grab credentials from that zip file that allow us to log into the CMS that we discovered, OffSec enjoys using publicly available exploits so we enumerate the version of the CMS that is running in order to find a vulnerability that allows us to simply upload a PHP reverse shell which gives us access to the box. We then use a privilege escalation script to identify what privilege escalation methods the machine is vulnerable to, and use a kernel vulnerability to escalate privileges. With all that being said, hope you enjoyed the proving grounds walkthrough!
