1) Introduction
===============


SnapStream PVS is a Personal Video Station software. It allows the user to
remotely
 schedule recordings and playing of Tv shows using video tapes and cable TV.

2) Bug
======

When the webserver hosting  SnapStream PVS LITE recieves a
'GET /?<script>alert('XSS')</script>' its ignores it, the data gets filtered
as it should.
But when it recieves a 'GET /?"><script>alert('XSS')</script>' the filters
are bypassed
and XSS appears and the server allows an attacker to inject & execute
scripts.
