CVE-2025-9838 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Student Information Management System (SIMS). 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 queries. This flaw enables remote exploitation without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the backend database, potentially allowing attackers to extract sensitive student data, modify records, or disrupt system operations. The CVSS 4.0 base score is 6.9, categorizing it as a medium severity issue. Although no known exploits are currently observed in the wild, a public exploit is available, increasing the risk of exploitation. The vulnerability arises from insufficient input validation or parameterized query usage in the affected PHP script, a common issue in web applications that interface with databases. Given the nature of the Student Information Management System, the compromised data could include personally identifiable information (PII), academic records, and other sensitive educational data, which are critical for privacy and regulatory compliance.

For European organizations, particularly educational institutions using the itsourcecode Student Information Management System, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive student and staff information, violating GDPR and other data protection regulations, potentially resulting in legal penalties and reputational damage. Integrity attacks could alter academic records or administrative data, undermining trust in institutional processes. Availability impacts could disrupt educational operations, affecting students and staff. The remote, unauthenticated nature of the exploit increases the threat landscape, as attackers can target vulnerable systems over the internet without prior access. This is especially critical for institutions with limited cybersecurity resources or outdated patch management practices. The presence of a public exploit further elevates the risk of automated or opportunistic attacks targeting vulnerable deployments across Europe.

To mitigate this vulnerability, European organizations should immediately audit their deployment of the itsourcecode Student Information Management System version 1.0 and identify any instances of the vulnerable component (/admin/modules/subject/index.php). Since no official patch links are provided, organizations should implement the following specific measures: 1) Apply input validation and sanitization on the 'ID' parameter to ensure only expected numeric or safe values are accepted. 2) Refactor database queries to use parameterized prepared statements or stored procedures to prevent SQL injection. 3) Restrict access to the vulnerable module by IP whitelisting or VPN access to reduce exposure. 4) Monitor web server logs for suspicious query patterns indicative of SQL injection attempts. 5) Employ Web Application Firewalls (WAFs) with rules designed to detect and block SQL injection payloads targeting the affected URL path. 6) Conduct penetration testing focused on injection flaws to verify remediation effectiveness. 7) Plan for upgrading to a newer, patched version of the software once available or consider alternative SIMS solutions with better security track records. 8) Educate administrators on secure configuration and incident response procedures related to web application attacks.
