'''
What does This Script Do:
  1. Send BXSS payload to site
  2. Wait until admin fires it
  3. Steal admin's session using BXSS script
  4. Using Admin's session, upload php shell
  5. Make a reverse TCP connection
  
Why does It need BXSS?
  1. Site contains file upload feature only in admin's panel.
  2. To upload a file we need to know credentials of admin or session
  3. BXSS used to steal admin's session to upload php file
