So I next attempt to SSH to the puppet host  and am presented with a possible username and a password hint in the SSH banner: Back to Google because I clearly do not have knightmare’s music knowledge and I see that Sandie Shaw’s most famous song was called ‘Puppet on a String’. Once I escalate to root I check out the root directory for a flag or our next clues. This was confirmed after attempting all upper and lowercase characters and receiving a 5 second delayed response on “S”, meaning that a password likely started with an “S”.

I throw a single quote in the username field and get the following error message: I’m feeling lazy so I throw it into sqlmap but something was being filtered in the back end. There were a few images left and the comment ‘images open doors’ was still burned in my mind so I pulled them down via Python 3 http.server (which btw I had to use because Knightmare removed the Python2 binary… thanks for that one 🙂 ).
