Vulnerability Information

Severity: Medium
Vulnerability Published: 2013-08-01
Patch Published: 2013-08-01
CVE [?]: CVE-2013-5576
CPE [?]: cpe:/a:joomla:joomla!

Synopsis

The remote web server contains a PHP application that is affected by a remote code execution vulnerability.

Description

According to its self-reported version number, the Joomla! installation running on the remote web server is 2.5.x prior to 2.5.14 or 3.x prior to 3.1.5. It is, therefore, affected by a remote code execution vulnerability due to a failure by the administrator/components/com_media/helpers/media.php script to properly validate the extension of an uploaded file. This allows files with '.php.' extensions to be uploaded and placed in a user-accessible path. An attacker can exploit this issue, via a direct request to such an uploaded file, to execute arbitrary PHP code with the privileges of the web server.

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

Solution

Upgrade to Joomla! version 2.5.14 / 3.1.5 or later. Alternatively, apply the patch referenced in the vendor advisory.
