These challenges were stupid simple because I’m sure the developers were ignorant to the fact that .phtml and .pht files existed. Upload your shell as a .phtml or .pht file and it’ll execute properly and let you pwn away. Keys are in /home/dwh/flags and /home/dwh_revenge/flags but you’ll need to use the “cat” command for the revenge challenge. I don’t know why I even made a writeup for this challenge since it was so terribly made.
Keep your hacks up and your head down
