CVE-2025-14640 is a SQL injection vulnerability identified in the code-projects Student File Management System version 1.0. 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 injection flaw can be exploited remotely without authentication or user interaction, enabling attackers to manipulate backend database queries. Potential consequences include unauthorized data retrieval, data modification, or deletion, which could compromise the confidentiality, integrity, and availability of student records managed by the system. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the vulnerability's remote exploitability and lack of required privileges, but limited scope and impact compared to critical vulnerabilities. No patches have been officially released, and no known exploits are currently active in the wild, but the availability of exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, suggesting that newer versions may have addressed this issue or that users should upgrade or apply custom mitigations. The Student File Management System is typically deployed in educational environments to manage student data, making the confidentiality and integrity of this data critical. Attackers exploiting this flaw could access sensitive student information or disrupt administrative functions, potentially leading to regulatory compliance issues and reputational damage.

For European organizations, particularly educational institutions using the affected Student File Management System, this vulnerability could lead to unauthorized access to sensitive student data, including personal identifiers and academic records. Such data breaches may violate GDPR and other data protection regulations, resulting in legal penalties and loss of trust. Integrity attacks could allow malicious actors to alter student records, impacting academic outcomes and institutional operations. Availability could also be affected if attackers execute destructive SQL commands or cause database corruption. The remote, unauthenticated nature of the exploit increases the risk of widespread attacks, especially in institutions with internet-facing administrative portals. The lack of current patches means organizations remain exposed until mitigations are applied. Additionally, the publication of exploit code may encourage opportunistic attackers targeting less-secure or unpatched systems across Europe. The impact extends beyond individual institutions to the broader educational ecosystem, potentially affecting student privacy and institutional credibility.

Immediate mitigation should focus on restricting access to the /admin/save_student.php endpoint, ideally limiting it to trusted internal networks or VPN users. Implementing web application firewalls (WAFs) with SQL injection detection rules can help block exploit attempts. Organizations should conduct code reviews and apply input validation and parameterized queries to sanitize the stud_no parameter, preventing injection. If vendor patches become available, prompt application is critical. In the absence of official patches, consider deploying database-level permissions to limit the impact of injected queries and monitoring database logs for suspicious activity. Regular backups of student data should be maintained to enable recovery in case of data corruption. Security teams should also educate administrators about the vulnerability and monitor threat intelligence feeds for emerging exploit activity. Finally, organizations should assess their exposure by inventorying deployments of the affected product and plan migration to updated or alternative solutions.
