> Is there a vBulletin Zero-day Out There?

Last Thursday the Inj3ct0r Team hacking group claimed on Twitter, "Inj3ct0r Team hacked http://vBulletin.com and http://Macrumors.com." By Friday vBulletin admitted the breach, and on Monday it was reported that a zero-day vulnerability used against both MacRumors and vBulletin had been put on sale by Inj3ct0r.
