CVE-2025-14622 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/save_user.php script, specifically in the handling of the 'firstname' parameter. Due to insufficient input validation or sanitization, an attacker can craft malicious SQL statements that are executed by the backend database. This flaw allows remote attackers to manipulate SQL queries without requiring any authentication or user interaction, enabling unauthorized access to or modification of sensitive student data stored in the database. 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 known exploits are currently active in the wild, the public release of exploit code increases the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, which is typically deployed in educational environments to manage student records. The absence of a patch or official fix at the time of disclosure necessitates immediate mitigation efforts to prevent exploitation.

For European organizations, especially educational institutions using the affected Student File Management System 1.0, this vulnerability poses a risk of unauthorized data disclosure, data tampering, and potential disruption of student record management. Attackers exploiting this flaw could extract sensitive personal information, alter student data, or corrupt the database, impacting confidentiality, integrity, and availability. Such breaches could lead to regulatory non-compliance under GDPR, reputational damage, and operational disruptions. The impact is heightened in countries with stringent data protection laws and where this software is widely used. Additionally, the remote and unauthenticated nature of the attack vector increases the risk of widespread exploitation if mitigations are not promptly applied.

1. Immediately restrict access to the /admin/save_user.php endpoint using network-level controls such as IP whitelisting or VPN access to limit exposure. 2. Implement input validation and sanitization on the 'firstname' parameter to reject or neutralize malicious SQL code. 3. Refactor the application code to use parameterized queries or prepared statements to prevent SQL injection. 4. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5. If possible, isolate the affected system within a segmented network zone to reduce lateral movement risks. 6. Engage with the vendor or community to obtain or develop a patch and apply it as soon as it becomes available. 7. Conduct security awareness training for administrators managing the system to recognize and respond to suspicious activities. 8. Regularly back up the database to enable recovery in case of data corruption or loss.
