"The version of ManageEngine SupportCenter Plus installed on the remote
host is affected by a cross-site scripting vulnerability because it
fails to properly sanitize user-supplied input to the 'fromCustomer'
parameter of the 'HomePage.do' script.  An attacker may be able to
leverage this to inject arbitrary HTML and script code into a user's
browser to be executed within the security context of the affected site. 

The application is reportedly also affected by an arbitrary file
upload vulnerability and a persistent cross-site scripting
vulnerability, although Nessus has not tested for these.");
