Official Compromised Discussion

Hey guys, need a little help here.
I’ve spent all day and could not progress. I am able to upload files, even managed to get a limited shell from there. I saw the user with shell that usually does not have it.
So I took a step back and managed to interact with the database as r**t. As far as I am aware of, I have f**_priv but I couldn’t do anything with it.

I’m thinking I’m losing myself in rabbit holes. Can anyone give me a hand?
