CVE-2026-2189 identifies a SQL injection vulnerability in the itsourcecode School Management System version 1.0, specifically within the /ramonsys/report/index.php file. The vulnerability arises from improper sanitization of the 'ay' parameter, allowing attackers to inject malicious SQL code remotely without authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized data access, modification, or deletion. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no known exploits in the wild have been reported, a public exploit is available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is typically deployed in educational environments to manage student and administrative data. The lack of patches currently necessitates alternative mitigations such as input validation and database access restrictions. This vulnerability highlights the importance of secure coding practices in web applications handling sensitive educational data.

For European organizations, particularly educational institutions using the itsourcecode School Management System 1.0, this vulnerability poses risks of unauthorized access to sensitive student and staff data, potential data manipulation, and disruption of reporting functionalities. Confidentiality could be compromised through data leakage, while integrity may be affected by unauthorized data modifications. Availability impacts are limited but possible if attackers manipulate queries to disrupt service. Given the remote and unauthenticated nature of the exploit, attackers could target multiple institutions without needing internal access. This could lead to reputational damage, regulatory non-compliance under GDPR due to data breaches, and operational disruptions. The medium severity suggests a moderate but tangible risk, especially in environments lacking compensating controls.

Organizations should prioritize applying official patches once released by itsourcecode. Until patches are available, implement strict input validation and sanitization on all user-supplied parameters, especially the 'ay' parameter in /ramonsys/report/index.php. Employ Web Application Firewalls (WAFs) with SQL injection detection rules to block malicious payloads. Restrict database user permissions to the minimum necessary to limit the impact of potential injection attacks. Conduct code reviews and penetration testing focused on injection flaws. Monitor logs for suspicious query patterns and unusual database activity. Educate developers on secure coding practices to prevent similar vulnerabilities. Consider isolating the affected system within the network and limiting external access until remediation is complete.
