Technical details
The login endpoint in adminpanel/admin/query/loginExe.php concatenates unsanitized POST parameters (username and password) directly into a SQL SELECT query without prepared statements or escaping. An attacker can inject SQL metacharacters such as ' OR '1'='1' -- - to bypass authentication and establish an admin session. The vulnerability is pre-authentication and network-accessible, requiring no user interaction or valid credentials.
