Both of POCs are working well (at least in my system -W2K3 all patches-)
after recent MS patches.

Can anyone confirm this ?

I can not. Wscript was deactivated with Guninski's WSH bug
a long time ago. I just tested running wscript in the My
Computer zone. It prompts as an unsafe activex.

However, Microsoft needs to get on the ball here and secure
that zone or make it trivial for their customers to do so. (Kudos
for their link on their security page, but that kind of
thing is targetted to IT professionals -- not to the masses...
and they can figure that out by themselves already.)

I also noticed the shell: path url does work as a source in
an iframe.

Once again, they are trying to patch the attack vector used instead of =
the
core IE problem itself (which is directly related to it being tied into =
the
OS level). I was once very pro-microsoft SMS Admin for my company but it =
is
getting out of hand.=20

If you patch a hole, instead of a vector, then L33tPrincess wouldn't be =
able
to add a couple of lines to the code and change the vector to make the
exploit workable in like 10 mins.

It is like they are throwing the media and the mass public trash "fix" =
to
make them happy while people like us shake our heads at what the public
doesn't know. The multiple patches for the same problem with different =
MS
numbers, it is a sad thing.

The fun is MS says we fixed "shell" but it's still active for me.

It's my fault; I had a bad configuration on my computer.
Now I see it's patched correctly and this POC is not working anymore on
fully patched windows.
