vBulletin Template Hack
Posted by on 02 July 2012 12:55 PM

Description of the Hack

One customer, who kept correcting the database table kept getting hacked repeatedly, even after updating to the latest vBulletin. His solution was to remove the spacer_open template:

"Since they're using the spacer_open template, I decided I should stop using it in the vB files. Apparently it is unnecessary. Here is how to remove it from use:

Now they can hack it all they want and nothing will happen. I put their hacked code back in the template to test it. Hopefully this "fixes" the problem until they find something else to exploit."
