**Name of the Vulnerable Software and Affected Versions** SourceCodester AC Repair and Services System version 1.0 **Description** A critical issue has been found in the system, affecting an unknown part of the file /classes/Master.php?f=save inquiry. The manipulation of the `id` argument leads to sql injection, and it is possible to initiate the attack remotely. **Recommendations** For version 1.0, consider disabling the `save inquiry` function in the Master.php file until a patch is available to prevent sql injection attacks. Restrict access to the /classes/Master.php?f=save inquiry endpoint to minimize the risk of exploitation. Avoid using the `id` argument in the affected endpoint until the issue is resolved.
