MediaWiki < 1.19.18 / 1.22.9 / 1.23.2 Multiple Vulnerabilities

medium Nessus Plugin ID 77183

Synopsis

The remote web server contains an 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 the following vulnerabilities :

- A flaw exists due to comments not being prepended to the JSONP callbacks. This allows a remote attacker, using a specially crafted SWF file, to perform a cross-site request forgery attack. (CVE-2014-5241)

- A cross-site scripting vulnerability exists within the 'mediawiki.page.image.pagination.js' script due to a failure to validate user-supplied input when the function 'ajaxifyPageNavigation' calls 'loadPage'. This allows a remote attacker, using a specially crafted request, to execute arbitrary script code within the trust relationship between the browser and server.
(CVE-2014-5242)

- A flaw exists with the iFrame protection mechanism, related to 'OutputPage' and 'ParserOutput', which allows a remote attacker to conduct a clickjacking attack.
(CVE-2014-5243)

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 1.19.18 / 1.22.9 / 1.23.2 or later.
