CVE-2025-9837 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Student Information Management System (SIMS). The vulnerability resides in the /admin/modules/student/index.php file, specifically in the processing of the 'studentId' parameter. An attacker can manipulate this parameter to inject malicious SQL code, which the system fails to properly sanitize or validate. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been observed in the wild yet. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. The vulnerability could enable attackers to read, modify, or delete sensitive student data stored in the database, potentially leading to data breaches, unauthorized data manipulation, or disruption of the student information system's availability. Given the critical role of student information systems in educational institutions, exploitation could also impact administrative operations and compliance with data protection regulations.

For European organizations, particularly educational institutions using the itsourcecode Student Information Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of student records and administrative data. Unauthorized access or modification of student information could lead to privacy violations under GDPR, resulting in legal and financial repercussions. The disruption of student management services could affect academic operations and institutional reputation. Since the attack requires no authentication and can be launched remotely, the threat surface is broad, especially for institutions with internet-facing management portals. The medium severity rating indicates a moderate but tangible risk, emphasizing the need for timely remediation to prevent potential data breaches or service interruptions.

1. Immediate patching: Although no official patch links are provided, organizations should contact itsourcecode or their software vendor to obtain security updates or patches addressing CVE-2025-9837. 2. Input validation and sanitization: Implement strict validation and sanitization of all input parameters, especially 'studentId', to prevent SQL injection. Use parameterized queries or prepared statements in the application code. 3. Web application firewall (WAF): Deploy a WAF with rules to detect and block SQL injection attempts targeting the vulnerable endpoint. 4. Network segmentation: Restrict access to the /admin/modules/student/index.php endpoint to trusted internal networks or VPN users to reduce exposure. 5. Monitoring and logging: Enable detailed logging of database queries and web requests to detect suspicious activity indicative of exploitation attempts. 6. Incident response readiness: Prepare to respond to potential breaches by backing up data regularly and having a plan for forensic analysis and recovery. 7. Security awareness: Train IT staff and administrators on the risks of SQL injection and the importance of timely updates and secure coding practices.
