## Technical details

A SQL injection vulnerability exists in Open ISES Tickets prior to version 3.44.2 within the 'message.php' component. The application fails to sanitize the 'frm_ticket_id' and 'frm_resp_id' POST parameters before concatenating them into SQL WHERE clauses for SELECT and UPDATE statements. An authenticated attacker with network access can exploit this by submitting specially crafted POST requests to manipulate database queries. Successful exploitation allows the attacker to read, modify, or delete database contents. The issue is resolved in version 3.44.2 by implementing proper input validation using functions like intval().
