Several flaws were found in Mediawiki: * (T117899) XSS from wikitext when $wgArticlePath='$1'. Internal review discovered an XSS vector when MediaWiki is configured with a non-standard configuration. <https://phabricator.wikimedia.org/T117899> * (T119309) User::matchEditToken should use constant-time string comparison. Internal review discovered that tokens were being compared as strings, which could allow a timing attack. This should possibly have 2 CVE's assigned, one for the original patch to use hash_equals in https://gerrit.wikimedia.org/r/#/c/156336/5/includes/User.php (released as part of MediaWiki 1.25, and backported to 1.24 and 1.23 as part of this patch) and one to fix T119309, related to the debugging statement. <https://phabricator.wikimedia.org/T119309> * (T118032) Error thrown by VirtualRESTService when POST variable starts with '@'. Internal review discovered that MediaWiki was not sanitizing parameters passed to the curl library, which could cause curl to upload files from the webserver to an attacker. <https://phabricator.wikimedia.org/T118032> * (T115522) Passwords generated by User::randomPassword() may be shorter than $wgMinimalPasswordLength. MediaWiki user Frank R. Farmer reported that the password reset token could be shorter than the minimum required password length. <https://phabricator.wikimedia.org/T115522> * (T97897) Incorrect parsing of IPs for global block. Wikimedia steward Vituzzu reported that blocking IP addresses with zero-padded octets resulted in a failure to block the IP address. <https://phabricator.wikimedia.org/T97897> * (T109724) A combination of Special:MyPage redirects and pagecounts allows an external site to know the wikipedia login of an user. Wikimedia user Xavier Combelle reported a way to identify user, when detailed page view data is also released. <https://phabricator.wikimedia.org/T109724> CVE request and original report: http://openwall.com/lists/oss-security/2015/12/21/8
