Solid machine. User may have been a bit much for some new guys, but overall, I thought everything was decently well thought out. Nothing was too difficult.
Foothold: CVE
User: Enumerate. The creds aren’t useless… Config files can also be useful. There are multiple ways to get user.
Root: Look through a smaller window, and you’ll see less.
Edit: If you message me for help, I will not respond unless you provide additional details regarding where/why you are stuck and what you have tried – thanks.
