Moodle 'post.php' 'reply' Parameter XSS

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The version of Moodle on the remote host contains a flaw that allows a
remote cross-site scripting attack due to the application not properly
validating the 'reply' variable on submission to the 'post.php'
script.

This allows a user to create a specially crafted URL that would
execute arbitrary code in a user's browser within the trust
relationship between the browser and the server, leading to a loss of
integrity.
