MediaWiki < 1.18.5 / 1.19.2 Multiple Vulnerabilities

high Nessus Plugin ID 62358

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 :

- A stored cross-site scripting (HTML injection) vulnerability exists because the application fails to sufficiently sanitize user-supplied input submitted to the 'File:' tag of a non-existing image through comments. (CVE-2012-4377)

- Multiple DOM-based cross-site scripting vulnerabilities exist because the application fails to sufficiently sanitize user-supplied input to the 'uselang' parameter and JavaScript gadgets on various language Wikipedias. (CVE-2012-4378)

- A cross-site request forgery (XSRF) vulnerability exists because the application fails to properly validate requests when X-Frame-Options headers are used. (CVE-2012-4379)

- A security-bypass vulnerability exists because the application fails to prevent the account creation for IP addresses blocked with the 'GlobalBlocking' extension.
(CVE-2012-4380)

- A security-bypass vulnerability exists because the application fails to prevent the use of old passwords in the external authentication system for non-existing accounts. (CVE-2012-4381)

- An information disclosure occurs when an admin attempts to block a user who has already been blocked. This discloses the block reason to the second admin, regardless of the admin's privileges. (CVE-2012-4382)

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 1.18.5 / 1.19.2 or later.
