Technical details
A SQL injection vulnerability exists in the 'haydi' parameter of the OnlineClearance/update_requirement_status.php file due to insufficient input validation and lack of prepared statements. The vulnerable parameter is processed directly into SQL queries without sanitization, allowing attackers to inject multiple SQL injection vectors including boolean-based blind, error-based, stacked queries, and time-based blind techniques. No authentication is required to exploit this vulnerability; an attacker can send a crafted HTTP POST request with malicious SQL payloads to achieve unauthorized database access, data exfiltration, modification, or deletion. Patch status is unknown; the advisory recommends implementing prepared statements with parameter binding, input validation, and restricting database user permissions.
