Summary:
Persistent cross-site scripting (XSS) in the web interface of Epson's TMNet WebConfig Ver 1.00 application allows a remote attacker to introduce arbitary Javascript via manipulation of an unsanitized POST parameter.

Steps to reproduce:

1)Make a POST request using Burp Proxy or other application 

------------------------------------------------------------------------------------------
POST /Forms/oadmin_1 HTTP/1.1
Host: XXX.XXX.XXX.XXX
