Re: [Full-disclosure] COM Server-Based Binary Planting ProofOfConcept

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.
