CVE-2025-14640 identifies a SQL injection vulnerability in the Student File Management System version 1.0 developed by code-projects. The vulnerability resides in the /admin/save_student.php script, where the stud_no parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This flaw can be exploited remotely without requiring authentication or user interaction, making it highly accessible to attackers. The injection can lead to unauthorized data access, modification, or deletion within the backend database, compromising sensitive student records. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, and no privileges or user interaction needed, but limited impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, the public availability of exploit code increases the likelihood of attacks. The vulnerability highlights the need for secure coding practices, particularly input validation and parameterized queries, to prevent injection flaws. The absence of vendor patches necessitates immediate mitigation efforts by administrators. Given the critical nature of educational data, exploitation could disrupt institutional operations and erode trust in data management systems.

For European organizations, particularly educational institutions using the affected Student File Management System, this vulnerability poses a significant risk to the confidentiality and integrity of student data. Exploitation could lead to unauthorized disclosure of personal information, manipulation of academic records, or deletion of critical data, impacting operational continuity and compliance with data protection regulations such as GDPR. The remote, unauthenticated nature of the attack vector increases the threat landscape, potentially allowing attackers to compromise systems without insider access. Disruption of student management systems could also affect administrative workflows and service delivery. Additionally, successful attacks might result in reputational damage and legal consequences for failing to protect sensitive data. Organizations relying on this software or similar legacy systems should prioritize vulnerability assessment and remediation to mitigate these risks.

1. Immediately audit and review the /admin/save_student.php code to identify and sanitize the stud_no parameter using parameterized queries or prepared statements to prevent SQL injection. 2. Implement Web Application Firewalls (WAFs) with rules specifically targeting SQL injection patterns to block malicious requests at the network perimeter. 3. Restrict access to administrative interfaces like /admin/save_student.php through network segmentation, VPNs, or IP whitelisting to reduce exposure. 4. Monitor database logs and application logs for unusual query patterns or repeated failed attempts that may indicate exploitation attempts. 5. Conduct comprehensive security testing, including automated scanning and manual penetration testing, to identify similar injection points. 6. Develop and deploy patches or updates from the vendor as soon as they become available; if unavailable, consider migrating to more secure, actively maintained software. 7. Educate development and IT teams on secure coding practices and the importance of input validation to prevent future injection vulnerabilities. 8. Ensure regular backups of critical data are maintained and tested to enable recovery in case of data corruption or deletion.
