Now, I'm not posting this solely out of altruism. I could use some help on the 'Mirrored Mayhem' task.
Spoiler Alert: Details about the challenge below
I've managed to get the RCE. I've crafted a PNG and successfully executed remote code. However, I'm only able to find the 'webapp-token'. I'm at a loss when it comes to the 'user-token' or 'root-token'. The 'whats in the mirror?' file isn't giving me any leads either. I've also got a username/password from it but can't figure out where to use them.Would appreciate any pointers or hints from anyone who's tackled this challenge. Thanks in advance!
