for the scriptkiddies to rejoice and the sysadmins to worry about.
to make sure [0x0D0D0D0D] == 0x0D0D0D0D. It's not the most efficient thing in the world but it works like a charm for
most IE bugs.
The BoF sets eax to 0x0D0D0D0D after which this code gets executed:
7178EC02 8B08 MOV ECX, DWORD PTR [EAX]
[0x0D0D0D0D] == 0x0D0D0D0D, so ecx = 0x0D0D0D0D.
7178EC04 68 847B7071 PUSH 71707B84
7178EC09 50 PUSH EAX
7178EC0A FF11 CALL NEAR DWORD PTR [ECX]
Again [0x0D0D0D0D] == 0x0D0D0D0D, so we jump to 0x0D0D0D0D.
We land inside one of the nopslide and slide on down to the shellcode. The shellcode is of the portbinding type, port
28876 to be exact. So now you know when to send me a happy birthday email...
The exploit will work with the <FRAME> and <IFRAME> tag, attached file uses <IFRAME>
For all you guys that cannot setup their AV software right, you can download the attachment from one of the many
mirrors of this list.
