CVE-2025-9839 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Student Information Management System (SIMS). The flaw exists in an unspecified function within the file /admin/modules/course/index.php, where manipulation of the 'ID' parameter allows an attacker to inject malicious SQL code. This vulnerability can be exploited remotely without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). The injection can lead to partial compromise of confidentiality, integrity, and availability of the backend database, as the vulnerability is rated with low impact on confidentiality, integrity, and availability (VC:L/VI:L/VA:L). The exploit code has been publicly released, increasing the risk of exploitation, although no known active exploitation in the wild has been reported yet. The vulnerability affects only version 1.0 of the product, which is a Student Information Management System used to manage academic data such as courses, student records, and grades. Given the nature of the system, successful exploitation could allow attackers to extract sensitive student data, modify academic records, or disrupt system operations. The CVSS 4.0 base score is 6.9, categorizing this as a medium severity vulnerability. The vulnerability does not require privileges or user interaction, making it easier to exploit, but the impact is somewhat limited by the low impact ratings on confidentiality, integrity, and availability, possibly due to partial sanitization or limited query scope. No patches or mitigation links have been published yet, so organizations must rely on other defensive measures until an official fix is available.

For European organizations, particularly educational institutions using the itsourcecode Student Information Management System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of student data. Exploitation could lead to unauthorized disclosure of personal information, including student identities, grades, and enrollment details, potentially violating GDPR and other data protection regulations. Integrity compromise could allow attackers to alter academic records, impacting students' academic progress and institutional reputation. Availability impact, while rated low, could still disrupt administrative operations if the database is manipulated or corrupted. The remote, unauthenticated nature of the exploit increases the threat level, as attackers can launch attacks from anywhere without needing credentials or user interaction. The public availability of exploit code further elevates the risk of opportunistic attacks. European educational institutions are often targeted due to the sensitive nature of their data and the critical role they play in society. Additionally, failure to secure such systems could lead to regulatory penalties and loss of trust from students and stakeholders.

Since no official patches or updates are currently available, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /admin/modules/course/index.php endpoint using network-level controls such as IP whitelisting or VPN access to limit exposure to trusted users only. 2) Implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ID' parameter. 3) Conducting thorough input validation and sanitization on all user-supplied parameters, especially the 'ID' argument, to prevent injection attacks. 4) Monitoring logs for unusual database queries or repeated failed attempts that may indicate exploitation attempts. 5) Isolating the SIMS environment from other critical systems to contain potential breaches. 6) Preparing for rapid patch deployment once an official fix is released by the vendor. 7) Educating administrative users about the risk and encouraging strong access controls and password policies. 8) Considering migration to alternative, actively maintained student information systems if feasible.
