Subject: Re: XSS Vulnerability in www.emerson.com

That... ahem... particular company has had that particular page
(/MCS/email.apsx) in one form or another for a long time, since the late
90s at least, when it was a cgi app.  

IIRC, at one time you could SPAM anyone through it, but they learned
their lesson and now you can only SPAM the company's employees.
Considering the business they're in (think "SCADA" related) this could
be a Bad Thing.  The XSS is just the icing on the cake.

I find it interesting that they "upgraded" it to SharePoint.

It's an in-house app, one of several.  I believe the security model used
to be "no one knows the URL".  

I'm guessing you're a contractor for that particular company because,
after all, no one knows the URL.
