Description:
The Simple Forum/Discussion System by (oretnom23) is vulnerable to remote SQL-Injection-Bypass-Authentication for the admin account in app admin_class.php.
remote SQL-Injection-Bypass-Authentication: https://portswigger.net/support/using-sql-injection-to-bypass-authentication.
The parameter (username) from the login form is not protected correctly and there is no security and escaping from malicious payloads.
When the user will sending a malicious query or malicious payload to the MySQL server, he can bypass the login credentials and take control of the admin account.
Vulnerable PHP part of code and all logic and architecture of the login form:
function login(){ extract($_POST); $qry = $this->db->query("SELECT * FROM users where username = '".$username."' and password = '".md5($password)."' "); if($qry->num_rows > 0){ foreach ($qry->fetch_array() as $key => $value) { if($key != 'passwors' && !is_numeric($key)) $_SESSION['login_'.$key] = $value; } return 1; }else{ return 3; } }
Simple fix but not correct and strong =)
function login(){ extract($_POST); $qry = $this->db->query("SELECT * FROM users where username = ('".$username."') and password = '".md5($password)."' "); if($qry->num_rows > 0){ foreach ($qry->fetch_array() as $key => $value) { if($key != 'passwors' && !is_numeric($key)) $_SESSION['login_'.$key] = $value; } return 1; }else{ return 3; } }
