CVE-2025-14646 is a SQL injection vulnerability identified in the Student File Management System version 1.0 developed by code-projects. The vulnerability resides in the /admin/delete_student.php script, specifically in the handling of the stud_id parameter. This parameter is vulnerable to SQL injection due to insufficient input validation or sanitization, allowing an attacker to inject malicious SQL statements remotely. The vulnerability can be exploited without any authentication or user interaction, making it accessible to unauthenticated remote attackers. Successful exploitation can lead to unauthorized data access, modification, or deletion within the backend database, impacting confidentiality, integrity, and availability of student records and potentially other sensitive data stored in the system. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The exploit code has been publicly released, increasing the likelihood of exploitation attempts. No patches are currently linked, so organizations must rely on interim mitigations such as input validation, use of prepared statements, and restricting access to the vulnerable administrative endpoint until an official fix is available.

For European organizations, especially 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, alteration or deletion of student records, and potential disruption of administrative operations. This could result in regulatory non-compliance, reputational damage, and operational downtime. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable systems from anywhere, increasing the attack surface. The public availability of exploit code further elevates the threat level. Organizations in Europe with limited cybersecurity resources or lacking timely patch management processes are particularly vulnerable. The impact extends beyond data loss to potential legal consequences under GDPR due to exposure of personal data.

1. Immediately restrict access to the /admin/delete_student.php endpoint by IP whitelisting or VPN access to limit exposure. 2. Implement strict input validation and sanitization on the stud_id parameter to reject malicious payloads. 3. Refactor the application code to use parameterized queries or prepared statements to prevent SQL injection. 4. Monitor web server and database logs for suspicious activity related to the stud_id parameter or unusual SQL queries. 5. Deploy Web Application Firewalls (WAFs) with rules targeting SQL injection patterns to provide an additional layer of defense. 6. Conduct a thorough security audit of the entire Student File Management System to identify and remediate other potential injection points. 7. Engage with the vendor or community to obtain and apply official patches or updates as soon as they become available. 8. Educate administrators on the risks and signs of exploitation to enable rapid detection and response.
