Description Ratul Gupta 2014-01-14 14:04:26 UTC

These flaws were fixed in the recently-released MediaWiki 1.22.1, 1.21.4, and 1.19.10 releases:

* MediaWiki user Michael M reported that the fix for bug 55332 (CVE-2013-4568) allowed insertion of escaped CSS values which could pass the CSS validation checks, resulting in XSS. (CVE-2013-6451)
<https://bugzilla.wikimedia.org/show_bug.cgi?id=58088>

* Chris from RationalWiki reported that SVG files could be uploaded that include external stylesheets, which could lead to XSS when an XSL was used to include JavaScript. (CVE-2013-6452)
https://bugzilla.wikimedia.org/show_bug.cgi?id=57550

* During internal review, it was discovered that MediaWiki's SVG sanitization could be bypassed when the XML was considered invalid. (CVE-2013-6453)
https://bugzilla.wikimedia.org/show_bug.cgi?id=58553

* During internal review, it was discovered that MediaWiki's CSS sanitization
did not filter -o-link attributes, which could be used to execute JavaScript in
Opera 12. (CVE-2013-6454)
https://bugzilla.wikimedia.org/show_bug.cgi?id=58472

* During internal review, it was discovered that MediaWiki displayed some information about deleted pages in the log API, enhanced RecentChanges, and user watchlists. (CVE-2013-6472)
