Serious Vulnerability Discovered in vBulletin

In the popular forum engine, vBulletin found an interesting vulnerability - when you type the word “database” in a search on the FAQ page, all information about connecting to MySQL server is displayed on the screen.

If you believe the developers - this bug was just an oversight, they forgot to remove part of the debug code from the engine.
