Moodle contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'name' parameter upon submission to the admin/webservice/service.php script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
