MediaWiki < 1.18.6 / 1.19.3 / 1.20.1 Multiple Vulnerabilities

medium Nessus Plugin ID 63267

Synopsis

The remote web server contains a PHP application that is affected by multiple vulnerabilities.

Description

According to its version number, the instance of MediaWiki running on the remote host is affected by multiple security vulnerabilities :

- MediaWiki core is vulnerable to session fixation attacks that allow an attacker to compromise another user's account. (CVE-2012-5391)

- The MediaWiki CentralAuth Extension is vulnerable to session fixation attacks. (CVE-2012-5395)

- An API feature in version 1.20 allows for HTML code to be injected in the 'editfont' option, resulting in cross-site scripting (XSS).

- A PCRE backtrack limit can be exceeded causing history pages to fail to display.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to MediaWiki version 1.18.6 / 1.19.3 / 1.20.1 or later.
