My advice for everyone is just to move on to another box. This is a complete CTF nightmare factory and is not realistic in any sense of the word. If you’re prepping for OSCP or trying to hone real-life pentesting skills, you are wasting your time here.

I don’t entirely agree with this, it’s a bit 50/50. Yes, the initial part is pretty silly and very very CTF. The getting shell part is something that can happen in real life. Then the creator made another poor choice with how to get the password (very ctf again).
I can see the Priv esc part happen in real life as well, because it is just poor scripting which does happen allot.
