Description Jan Lieskovsky 2012-08-31 13:08:46 UTC
Multiple DOM-based cross-site scripting (XSS) flaws were found in the way MediaWiki, a wiki engine, performed filtering of the uselang parameter. When JavaScript gadgets were used, a remote attacker could provide a specially-crafted URL that, when visited would lead to arbitrary HTML or web script execution.
