I tried SQLi 2 for some time but I can't figure it out, even though I believe it isn't that hard, and tried plenty of methods. No matter what I do, I get "You do not have sufficient privileges to see this information." which seems so strange.
I will try even harder, but just to be sure - is the database working properly?
I just checked it and it worked fine for me.
Could I get some sort of a hint? I type Admin as user and then try plenty of ways to inject always true statement in password. To avoid the filters I tried from very simple (upper/lower case letters) to more refined methods like in there: https://websec.wordpress.com/tag/sql-filter-bypass/
I still get the privileges error, I really don't know what am I missing.
EDIT: Wow, that is so incredible, that the first try after writing this post proved to be correct (using NBP). I still don't know why other methods didn't work tho...
