MediaWiki CSS data cross-site scripting
|mediawiki-css-data-xss (66738)||Medium Risk|
MediaWiki is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the wikitext parser when handling CSS data. A remote attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
Upgrade to the latest version of MediaWiki (1.16.4 or later), available from the MediaWiki Web site. See References.

- CVE-2011-1579: The checkCss function in includes/Sanitizer.php in the wikitext parser in MediaWiki before 1.16.3 does not properly validate Cascading Style Sheets (CSS) token sequences, which allows remote attackers to conduct cross-site scripting (XSS) attacks or obtain sensitive information by using the \2f\2a and \2a\2f hex strings to surround CSS comments.
