"The version of Symantec Endpoint Protection Manager running on the
remote web server is affected by a cross-site scripting (XSS)
vulnerability due to improper sanitization of input to the 'Msg'
parameter in the TestConnection.jsp file. An unauthenticated, remote
attacker can exploit this vulnerability by convincing a user to make a
malicious request, resulting in the execution of arbitrary script code
in the user's browser session.

This version of Endpoint Protection Manager is affected by additional
XSS and XSRF vulnerabilities; however, Nessus has not tested for
these.");
