Is the exploit only for when running services on/to the internet (IIS, Exchange webmail, etc - ) , or is visiting an https (TLS) website on and end-user enough to make the exploit happen (even in Firefox/Chrome and behind a tradional proxy server).
Sadly Microsoft does not explain the exact parameters that make this exploit tick - this makes risk assessment hard.
