Not a problem, Tim; I'm always up to find the guy who can actually break
through ISA...

That's cool... I didn't really think you could share it if you had it. :)
I'm sure I'll be getting my hands on actual exploit code soon, so I too will
try it against the pub rules.  Not that I don't trust your tool, but I just
want to make sure, you know?

MSRC handed me a test app, which I'm not at liberty to share (obviously).
Sorry..  I know there are more honest folks trying to validate their
security than there are h2x0rs trying to create the next worm, but NDA
constraints and all that.

Indeed. But, how exactly did you test that, Jim?  Do you have some exploit
code hidden away somewhere?  Care to share Big Boy???

..hmmmm..  seems you is right.
Still, it's nice to know that ISA blocks it even when publishing RPC...

Saw your comments on my article.  Thanks for providing that info about
publishing RPC and ISA's protection of it.

I know now that it is indeed exploitable over TCP 135 *and* UDP 135-- I got
confirmation from LSD on that...  Though we are all protected, I am still
very worried about this one... This is a class exploit, and if/when a
multi-vector worm is written, it will make slammer look like a fin packet.
