This vulnerability involves an SQL injection in the delete.php file of the raisulislamg4 student_management_system_by_php. Specifically, the injection occurs when an attacker manipulates one of the parameters (user_id, course_id, teacher_id, student_id, application_id) passed to an unknown function, allowing unauthorized SQL commands to be executed. The vulnerability is remotely exploitable without privileges or user interaction. The product is maintained via rolling releases, so no specific versioning details are available. No official patch or remediation guidance has been issued by the vendor as of the publication date.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access, modification, or deletion. Since the vulnerability is remotely exploitable without authentication, it poses a significant risk to the confidentiality and integrity of the system's data. However, no evidence of active exploitation in the wild has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no official fix is available, users should consider implementing temporary mitigations such as input validation and parameterized queries if possible. Monitoring for unusual database activity and restricting access to the vulnerable delete.php endpoint may also reduce risk until a patch is released.
