CVE-2025-14620 identifies a SQL Injection vulnerability in the Student File Management System version 1.0 developed by code-projects. The vulnerability resides in the /admin/login_query.php script, specifically in the handling of the Username parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code due to insufficient input sanitization and lack of prepared statements. This allows unauthorized execution of arbitrary SQL commands against the backend database, potentially leading to unauthorized data disclosure, data modification, or even complete system compromise. The vulnerability requires no authentication or user interaction, making it easier to exploit remotely. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based, with low complexity and no privileges required, but with limited impact on confidentiality, integrity, and availability. No patches or official fixes have been published yet, and no known exploits are reported in the wild, but the public disclosure increases the risk of exploitation by threat actors. The vulnerability is particularly critical for organizations managing sensitive student data, as exploitation could lead to exposure of personal information or disruption of educational services.

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 records and administrative data. Exploitation could lead to unauthorized access to sensitive personal information, including student identities, grades, and other academic records, potentially violating GDPR and other data protection regulations. Integrity of data could be compromised, allowing attackers to alter records or escalate privileges within the system. Availability impact is limited but possible if attackers execute destructive SQL commands. The reputational damage and regulatory penalties resulting from data breaches could be severe. Given the remote and unauthenticated nature of the attack, the threat is accessible to a wide range of attackers, increasing the urgency for mitigation. The vulnerability could also be leveraged as a foothold for further network intrusion within educational or administrative environments.

1. Immediately implement input validation and sanitization on the Username parameter in /admin/login_query.php to reject malicious input. 2. Refactor the code to use parameterized queries or prepared statements to prevent SQL injection. 3. Restrict network access to the administrative interface to trusted IP addresses or VPNs to reduce exposure. 4. Monitor database logs and application logs for unusual or suspicious SQL queries indicative of exploitation attempts. 5. Conduct a thorough security audit of the entire Student File Management System to identify and remediate any additional injection points. 6. If patching is not immediately possible, consider deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection patterns targeting the Username parameter. 7. Educate system administrators and developers on secure coding practices to prevent similar vulnerabilities. 8. Prepare an incident response plan in case exploitation is detected, including data breach notification procedures compliant with GDPR.
