CVE-2025-7600 is a SQL Injection vulnerability identified in version 3.0 of the PHPGurukul Online Library Management System, specifically in the /admin/student-history.php file. The vulnerability arises from improper sanitization or validation of the 'stdid' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without authentication or user interaction to inject malicious SQL code. This can lead to unauthorized access to the backend database, allowing attackers to read, modify, or delete sensitive data related to student histories or other stored information. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS 4.0 score is 5.3 (medium severity), reflecting a network attack vector with low complexity and no required privileges or user interaction, but with limited impact on confidentiality, integrity, and availability. The vulnerability does not involve scope changes or security controls bypass, indicating the attack affects only the vulnerable component. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate mitigation steps.

For European organizations using PHPGurukul Online Library Management System 3.0, this vulnerability poses a risk of data breach and integrity compromise within their library management infrastructure. Exploitation could lead to unauthorized disclosure of student records and other sensitive data, potentially violating GDPR and other data protection regulations. The integrity of records could be compromised, affecting operational trustworthiness and reporting accuracy. Although the CVSS score is medium, the ease of remote exploitation without authentication increases the risk profile. Organizations relying on this system for academic or public library services may face reputational damage, legal penalties, and operational disruptions if exploited. The absence of known exploits in the wild currently reduces immediate threat but does not eliminate the risk, especially given the public disclosure. The impact on availability is limited but could occur if attackers modify or delete critical data.

European organizations should immediately audit their use of PHPGurukul Online Library Management System to identify affected installations running version 3.0. Until an official patch is released, organizations should implement strict input validation and sanitization on the 'stdid' parameter at the web application firewall (WAF) or reverse proxy level to block SQL injection payloads. Employing parameterized queries or prepared statements in the application code is the definitive fix and should be prioritized once patches are available. Monitoring database logs and web server logs for unusual query patterns or injection attempts is recommended. Restricting access to the /admin/student-history.php endpoint via IP whitelisting or VPN access can reduce exposure. Regular backups of the database should be maintained to enable recovery in case of data tampering. Organizations should also consider isolating the library management system from critical network segments to limit lateral movement if compromised.
