Silo sanity check

Wondering if some one who has rooted this can help me validate what Iam seeing. I enumerate a certain service and find several interesting items I use them to enumerate further and find a interesting account. From there I try to use that account and it does not work. Dont want to spoil anything so if you have root and I can message you it be greatly appreciated. Iam not sure if my tool is borked or iam diging down the rabit hole.

Hi can give a hint on initial foothold, i log in into the database, should i create a store procedure to call a shell?
