The code-projects Student File Management System 1.0 is vulnerable to unauthenticated remote SQL injection, which could allow attackers to manipulate database queries.

This vulnerability is a SQL injection (CWE-89) located in the /admin/update_student.php file. The flaw allows an unauthenticated remote attacker to inject malicious SQL commands by manipulating the stud_id argument.

The exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive student records, potential data modification, or the compromise of the underlying database integrity. With a CVSS score of 7.3, this represents a high-severity risk that could lead to significant data exposure and loss of confidentiality within the management system.

Immediate Action: Since no official patch is currently available, administrators should restrict network access to the /admin/ directory using IP allowlisting or VPN requirements.

Proactive Monitoring: Security teams should review web server access logs for suspicious patterns in the stud_id parameter, particularly strings containing SQL keywords or special characters.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to block common SQL injection patterns targeting the update_student.php endpoint.

Public Exploit Available: Yes, a published proof-of-concept exists as documented in the linked GitHub repository.

Given the availability of a public proof-of-concept and the ease of exploitation, this vulnerability poses a credible threat to the integrity of the Student File Management System. Administrators must prioritize limiting exposure by restricting access to the administrative interface and implementing strict input validation or WAF protections until a vendor-supplied patch is released.
