the things that must be considered that the POC it's variant from exploit to
exploit(some times
Kaspersky and the other famous AV Sofware can be deceive).
Proof Of Concept:
as i said the exploit are based on the magic of magic byte methode we will
first add the MZ Header to the HTML Exploit and change the exstention to txt
or jpg or non extension,the exploit is compatible with IE6 and IE7 because
IE6&7 execute the HTML Event if it's in txt file or non extension files.
so the exploit it's with corporate of IE6&7 :).

and this is a Variant one "obfuscated by this methode".

POC:
1-add the MZ Header to the HTML file:
MZگ ےے ¸ @
ط ؛ ´ ح!¸Lح!This program cannot be run in DOS mode.
you can put other EXE info on the HTML Body for more deception "showing in the
second result".
-rename the HTML to non extension file or txt or jpg.
3-upload it to webserver.
http://localhost/mallpage.txt or http://localhost/mallpage<non extenstion>.
