CVE-2025-9839 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Student Information Management System (SIMS). The flaw resides in an unspecified function within the file /admin/modules/course/index.php, where manipulation of the 'ID' argument allows an attacker to inject malicious SQL commands. This vulnerability is remotely exploitable 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 underlying database, as the CVSS vector indicates 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 typically used by educational institutions to manage student data, courses, and related administrative functions. Given the nature of the vulnerability, an attacker could potentially extract sensitive student data, modify records, or disrupt system operations by executing arbitrary SQL queries against the backend database. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate mitigation measures.

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 records and administrative data. Exploitation could lead to unauthorized disclosure of personal data protected under GDPR, resulting in legal and reputational consequences. Integrity violations could disrupt academic records, course enrollments, or grading information, impacting operational continuity and trust. Availability impacts, while rated low, could still manifest through database corruption or denial of service caused by malicious queries. The public availability of exploit code increases the likelihood of opportunistic attacks, especially against less-secured or unpatched systems. Given the critical role of student information systems in educational workflows, exploitation could also indirectly affect staff and students by interrupting access to essential services. Furthermore, data breaches involving minors or sensitive educational data could attract regulatory scrutiny and fines under European data protection laws.

Immediate mitigation should focus on input validation and sanitization of the 'ID' parameter in /admin/modules/course/index.php to prevent injection of malicious SQL code. Implementing prepared statements or parameterized queries is essential to eliminate direct concatenation of user input into SQL commands. If source code modification is not feasible immediately, deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection patterns targeting the vulnerable parameter can provide temporary protection. Organizations should also conduct a thorough audit of all input handling in the application to identify and remediate similar injection points. Monitoring database logs for suspicious queries and unusual access patterns can help detect exploitation attempts early. Since no official patch is currently available, organizations should engage with the vendor for updates or consider upgrading to a newer, unaffected version if available. Additionally, restricting network access to the administrative module to trusted IP addresses and enforcing strong authentication controls can reduce exposure. Finally, organizations must ensure that regular backups of the database are maintained and tested for restoration to mitigate potential data loss or corruption.
