Rooted a few days ago, funny and not so easy box. Name of the machine is a big hint. For the foothold, enumeration with different wordlists is the key. Then you’ll find some files with useful information in order to understand how the site is built. Read carefully also the comments left in those files, connect the dots and google will be your best friend. There’s a huge vulnerability that can be used to retrieve other informations. Then it’s pretty easy to get user. Escalation to root will require another bit of effort, but looking at what you can do with your user will help a lot. Try to work on it!
Hope this is not a spoiler, if you need some nudges PM me and let me know what you’ve already tried!
