# 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 --- #
