Description Jan Lieskovsky 2012-08-31 14:04:25 UTC

A security flaw was found in the way MediaWiki, a wiki engine, performed account creation capability validation for certain IP addresses (IP addresses blocked with GlobalBlocking extension were incorrectly still allowed to create new user accounts). A remote attacker could use this flaw to circumvent the GlobalBlocking account creation prevention mechanism.
