[原文]Multiple cross-site scripting (XSS) vulnerabilities in MediaWiki before 1.4.9 allow remote attackers to inject arbitrary web script or HTML via (1) <math> tags or (2) Extension or <nowiki> sections that "bypass HTML style attribute restrictions" that are intended to protect against XSS vulnerabilities in Internet Explorer clients.
MediaWiki contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the '<math>' tags. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
Upgrade to version 1.4.9 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
