CVE-2025-6914 is a SQL Injection vulnerability identified in version 3.2 of the PHPGurukul Student Record System, specifically within the /edit-student.php file. The vulnerability arises from improper sanitization or validation of the 'fmarks2' parameter, which is susceptible to malicious SQL code injection. An attacker can exploit this flaw remotely without requiring user interaction or authentication, allowing them to manipulate backend database queries. This can lead to unauthorized data access, modification, or deletion within the student record system's database. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild. The CVSS 4.0 base score is 5.3, indicating a medium severity level, reflecting limited impact on confidentiality, integrity, and availability, and requiring low privileges but no user interaction. The vulnerability does not affect system components beyond the specific PHP script, and no patches or mitigations have been officially released at the time of reporting.

For European organizations, particularly educational institutions or administrative bodies using the PHPGurukul Student Record System, this vulnerability poses a risk of unauthorized access to sensitive student data, including grades and personal information. Exploitation could lead to data breaches, manipulation of academic records, and potential compliance violations under GDPR due to exposure of personal data. The ability to remotely exploit the vulnerability without authentication increases the threat level, especially for institutions with internet-facing installations of the affected system. While the medium severity suggests limited immediate damage, the potential for data integrity compromise and reputational harm is significant. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within organizational IT infrastructure.

Organizations should immediately audit their use of PHPGurukul Student Record System version 3.2 and restrict external access to the /edit-student.php endpoint through network segmentation or firewall rules. Input validation and parameter sanitization should be implemented or enhanced for the 'fmarks2' parameter to prevent SQL injection. Employing Web Application Firewalls (WAFs) with SQL injection detection rules can provide a temporary protective layer. Monitoring logs for unusual database query patterns or access attempts targeting the vulnerable parameter is advised. Since no official patch is available, organizations should consider upgrading to a newer, secure version once released or migrating to alternative student record systems with robust security. Regular backups of student data should be maintained to enable recovery in case of data tampering. Finally, educating administrators and developers about secure coding practices and prompt vulnerability management is essential to prevent similar issues.
