CVE-2026-2190 is a SQL injection vulnerability identified in the itsourcecode School Management System version 1.0, specifically within an unknown function located in the /ramonsys/user/controller.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which can be manipulated by remote attackers to inject arbitrary SQL commands. This injection flaw allows attackers to execute unauthorized database queries, potentially leading to unauthorized data disclosure, modification, or deletion. The attack vector is network-based, requiring no authentication or user interaction, making exploitation straightforward. The vulnerability has been assigned a CVSS 4.0 score of 6.9, indicating a medium severity level due to its ease of exploitation and moderate impact on confidentiality, integrity, and availability. Although no active exploitation has been reported in the wild, the public release of an exploit increases the likelihood of attacks. The affected software is used in educational environments, where sensitive student and staff data may be stored, raising concerns about data privacy and operational disruption. The lack of available patches necessitates immediate mitigative actions by administrators. The vulnerability highlights the critical need for secure coding practices such as input validation, parameterized queries, and thorough security testing in web applications managing sensitive data.

For European organizations, particularly educational institutions using the itsourcecode School Management System 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of sensitive educational data. Exploitation could lead to unauthorized access to student records, staff information, and other critical data, potentially resulting in data breaches and regulatory non-compliance under GDPR. The ability to remotely exploit the flaw without authentication increases the attack surface and risk of widespread compromise. Disruption of school management operations could affect administrative functions, scheduling, and communication, impacting educational delivery. The public availability of an exploit increases the likelihood of opportunistic attacks, including data theft, defacement, or ransomware deployment. European organizations may also face reputational damage and financial penalties if the vulnerability is exploited. The medium severity rating suggests that while the impact is serious, it may not lead to full system compromise without additional vulnerabilities or misconfigurations. Nonetheless, the threat is non-negligible given the critical nature of educational data and services.

Organizations should immediately conduct a thorough code audit of the /ramonsys/user/controller.php file to identify and remediate the SQL injection vulnerability. Specifically, developers must implement strict input validation and sanitization for the 'ID' parameter, ensuring only expected data types and values are accepted. The use of parameterized queries or prepared statements is essential to prevent injection attacks. In the absence of an official patch, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block malicious SQL injection payloads targeting the vulnerable endpoint. Network segmentation and restricting external access to the management system can reduce exposure. Regularly monitor logs and network traffic for unusual queries or access patterns indicative of exploitation attempts. Educate IT staff and users about the vulnerability and encourage prompt reporting of suspicious activity. Plan for timely updates once an official patch is released by the vendor. Additionally, conduct penetration testing to verify the effectiveness of mitigations and overall system security posture.
