Rooted. Struggled a while on the foothold after I got around all my 502 errors.
User was easy.
Root was funny because whenever i cat’d a certain file, I didn’t see what I needed to see to privesc. Idk if my terminal was messed up or something, but I was very confused because I was very confident that this was part of the privesc, but I didn’t see anything worthwhile.
Finally figured it out, though. Fun box! Thanks!
