MediaWiki CSS Comments XSS
Medium Nessus Plugin ID 51998
Synopsis
The remote web server hosts a version of MediaWiki vulnerable to a cross-site scripting attack.
Description
There is a cross-site scripting vulnerability in this installation of MediaWiki that may allow an attacker to execute arbitrary script code in the browser of an unsuspecting user. Such script code could steal authentication credentials and be used to launch other attacks.
This version of MediaWiki also contains a local file inclusion vulnerability that is exploitable when running Microsoft Windows, but this plugin did not test for that vulnerability.
Solution
Upgrade to MediaWiki 1.16.2 or later.
