Description

Several vulnerabilities were discovered in MediaWiki, a wiki engine. The Common Vulnerabilities and Exposures project identifies the following issues:

CVE-2013-2031 Cross-site scripting attack via valid UTF-7 encoded sequences in a SVG file.

CVE-2013-4567 & CVE-2013-4568 Kevin Israel (Wikipedia user PleaseStand) reported two ways to inject Javascript due to an incomplete blacklist in the CSS sanitizer function.

CVE-2013-4572 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-2013-6452 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-2013-6453 MediaWiki's SVG sanitization could be bypassed when the XML was considered invalid.

CVE-2013-6454 MediaWiki's CSS sanitization did not filter -o-link attributes, which could be used to execute JavaScript in Opera 12.

CVE-2013-6472 MediaWiki displayed some information about deleted pages in the log API, enhanced RecentChanges, and user watchlists.

CVE-2014-1610 A remote code execution vulnerability existed if file upload support for DjVu (natively handled) or PDF files (in combination with the PdfHandler extension) was enabled. Neither file type is enabled by default in MediaWiki.

CVE-2014-2665 Cross site request forgery in login form: an attacker could login a victim as the attacker.
