CVE-2025-9838 is a SQL Injection vulnerability identified in the itsourcecode Student Information Management System version 1.0. The vulnerability exists in an unspecified function within the file /admin/modules/subject/index.php, where manipulation of the 'ID' parameter allows an attacker to inject malicious SQL code. This flaw enables an attacker to execute arbitrary SQL queries on the backend database remotely without requiring authentication or user interaction. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact affects confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L). The scope remains unchanged (S:U). Although no known exploits are reported in the wild yet, public exploit code is available, increasing the risk of exploitation. The vulnerability could allow attackers to extract sensitive student data, modify records, or disrupt system availability by executing crafted SQL commands. Given the nature of student information systems, this could lead to unauthorized disclosure of personal data, data tampering, and potential compliance violations 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. Exploitation could result in unauthorized access to personally identifiable information (PII), academic records, and potentially financial data related to tuition or scholarships. This could lead to reputational damage, legal liabilities under GDPR, and operational disruptions. The ability to remotely exploit the vulnerability without authentication increases the threat landscape, especially for institutions with internet-facing management portals. Additionally, data integrity compromise could affect academic processes and decision-making, while availability impacts could disrupt administrative functions. The medium severity rating suggests a moderate but tangible risk that requires timely remediation to prevent exploitation.

Specific mitigation steps include: 1) Immediate application of patches or updates from the vendor once available; since no patch links are currently provided, organizations should monitor vendor advisories closely. 2) Implement input validation and parameterized queries or prepared statements in the affected module to prevent SQL injection. 3) Restrict access to the /admin/modules/subject/index.php endpoint by IP whitelisting or VPN access to reduce exposure. 4) Employ Web Application Firewalls (WAFs) with SQL injection detection rules tailored to the specific patterns of this vulnerability. 5) Conduct thorough code reviews and penetration testing focusing on input handling in the Student Information Management System. 6) Monitor logs for suspicious SQL query patterns or unusual access to the vulnerable endpoint. 7) Educate IT staff and administrators about the risks and signs of exploitation attempts. 8) If feasible, isolate the student information system from direct internet exposure and enforce strong network segmentation.
