Joomla! 'lang' Parameter XSS

medium Nessus Plugin ID 69280

Synopsis

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

Description

The version of Joomla! running on the remote host is affected by a cross-site scripting (XSS) vulnerability in idna_convert/example.php due to improper sanitization of user-supplied input to the 'lang' parameter before using it to generate dynamic HTML content. An unauthenticated, remote attacker can exploit this to inject arbitrary HTML and script code into the user's browser session.

Solution

Unknown at this time. It is suggested that the script be removed.
