Joomla! 2.5.x < 2.5.7 Multiple XSS

medium Nessus Plugin ID 64438

Synopsis

The remote web server contains a PHP application that is affected by multiple cross-site scripting vulnerabilities.

Description

According to its self-reported version number, the Joomla! installation running on the remote web server is 2.5.x prior to 2.5.7.
It is, therefore, affected by multiple cross-site (XSS) scripting vulnerabilities :

- A cross-site scripting (XSS) vulnerability exists in the default_system.php script due to improper validation of the User-Agent string before submitting it to the sysinfo.php script. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2012-4351)

- A cross-site scripting (XSS) vulnerability exists in the Language Switcher module, specifically within file modules/mod_languages/tmpl/default.php, due to improper sanitization of input passed via 'PATH_INFO' to the index.php script. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2012-4352)

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 Joomla! version 2.5.7 or later. Alternatively, apply the patch referenced in the vendor advisory.
