Enumeration

Researching this vulnerability we are going to have to do the following:

  • Configure exploit to connect to a port on our attack machine

  • Set up an httpserver with nc.exe running

  • set up our listening

  • Run the python code

This exploit will grab the nc.exe from our server (port 80) execute it and run it and connect it to our attack machine. Further research of the exploit can be found here:
