So a while ago, my friend and I started trying to look into a vulnerable sql page to do with a donation addon called Prometheus, the link we used was
http://www.lumberdashjack.com/donate/store.php?id=1 , we used havij to dig into it but after a while we got lazy and stopped, if any of you want to continue with it go ahead. The db's i can remember is donations,information_schema,darkrp and dayz. good luck, i hope u find something
