Hi Vince!

I think this article from CERT will help you a lot. It contains description, impact and user solutions to XSS attacks. 
However the best is to fix the vulnerability at your site, depending of situation you can be exposing your customers to 
thighs going from disgusting images to sensitive information stealth.

cheers :)

Hi all,
        I was running a routine nessus scan on some servers i administrate
and one of them gave me a warning of

The following requests seem to allow the reading of
sensitive files or XSS. You should manually try them to see if anything bad
happens : 
/default.asp?gateway=<script>alert('foo')</script>

I tried that and it worked, I forwarded it to a developer for that machine
and he didnt seem worried by it. Should he be ?
A bit vague i know but webapps arent realy my forte.

Thanks,
Vince
