Descriptions

Incomplete blacklist vulnerability in Sanitizer::checkCss in MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 allows remote attackers to conduct cross-site scripting (XSS) attacks via a \b (backspace) character in CSS.

Vulenrabilidad de lista negra incompleta en Sanitizer::checkCss en MediaWiki anterior a 1.19.9, 1.20.x anterior a 1.20.8 y 1.21.x anterior a 1.21.3 que permite a atacantes remotos realizar cross-site scripting (XSS) a través de un \b (retroceso carácter) en el CSS.

Kevin Israel identified and reported two vectors for injecting Javascript in CSS that bypassed MediaWiki's blacklist. Internal review while debugging a site issue discovered that MediaWiki and the CentralNotice extension were incorrectly setting cache headers when a user was autocreated, causing the user's session cookies to be cached, and returned to other users.
