Two things:

1) Are you sure a stock build of Windows doesn't pop a security
warning when right clicking the file:// IFRAME?  You might have munged
your test OS.
2) You're getting closer with this "Send To" stuff, but you're still
socially engineering.  Definitely better than classic "please download
and execute this file" though.

You really should stop talking about exploits against Powerpoint etc.
As long as I can make an .exe that visually looks pixel for pixel like
a .ppt, the security model you imagine (that the desktop can
differentiate between code execution and document editing) doesn't
exist.  This work is better, if incomplete.

Thor, the "Online Proof of Concept" section of the blog post points you to a *remote*
exploit (without any warning) but let me repeat the link here:

http://www.binaryplanting.com/demo/XP_2-click/test.html

Visit this with IE8 on 32-bit Windows XP.

Please find further information here:

In general there are two types of remote binary planting exploits: SMB and WebDAV.
The former works inside (local) networks where firewalls block outbound SMB traffic.
WebDAV attacks work through firewalls too since many firewalls allow outbound WebDAV
traffic and Windows silently fall back to WebDAV if SMB doesn't work. If our online
remote exploit doesn't work for you, you can download the PoC locally and test it in
your local network.

I'll be happy to explain it to you further if need be.

Thanks,
Mitja

But it *is* worth mentioning that you have to create the
malicious dll file, copy it to the system, create folders
etc, and all the other mumbo jumbo to "exploit" this in the
"default configuration."   So, the answer to Dan's question
is actually, "no, you can't."  Which brings into question the
actual "worth" of mentioning this in the first place. :)

It would hardly be worth mentioning otherwise.

Does this run code without prompting, on a reasonably default
configuration?

Feel free to try it out online if WebDAV works through your
firewall,
or download it and test it in your local network or simply
on your computer.
