Description

  • Kevin Israel (Wikipedia user PleaseStand) identified and reported two vectors for injecting JavaScript in CSS that bypassed MediaWiki's blacklist (CVE-2013-4567, CVE-2013-4568). <https://bugzilla.wikimedia.org/show_bug.cgi?id=55332>

  • 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 (CVE-2013-4572). <https://bugzilla.wikimedia.org/show_bug.cgi?id=53032>

Additionally, the following extensions have been updated to fix security issues :

  • CleanChanges: MediaWiki steward Teles reported that revision-deleted IP's are not correctly hidden when this extension is used (CVE-2013-4569). <https://bugzilla.wikimedia.org/show_bug.cgi?id=54294>

  • ZeroRatedMobileAccess: Tomasz Chlebowski reported an XSS vulnerability (CVE-2013-4573). <https://bugzilla.wikimedia.org/show_bug.cgi?id=55991>

  • CentralAuth: MediaWiki developer Platonides reported a login CSRF in CentralAuth (CVE-2012-5394). <https://bugzilla.wikimedia.org/show_bug.cgi?id=40747>

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
