CVE-2026-1551 identifies a SQL injection vulnerability in the itsourcecode School Management System version 1.0, specifically in the /ramonsys/course/controller.php file. The vulnerability arises from improper validation and sanitization of the 'ID' parameter, which is used directly in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. The vulnerability does not require authentication or user interaction, increasing its risk profile. The CVSS 4.0 score is 5.3 (medium), reflecting the ease of remote exploitation but limited scope and impact. The vulnerability could lead to unauthorized data disclosure, data modification, or denial of service if exploited. Although no active exploitation has been reported, the public availability of exploit code increases the likelihood of attacks. The lack of available patches necessitates immediate mitigation efforts. This vulnerability is critical for educational institutions relying on this software for managing sensitive student and administrative data. Attackers could leverage this flaw to extract personal information, alter academic records, or disrupt school operations.

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 student and administrative data. Exploitation could lead to unauthorized disclosure of personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Data manipulation could undermine academic record integrity, affecting students and staff. Additionally, disruption of school management systems could impact operational continuity. The remote, unauthenticated nature of the exploit increases the risk of widespread attacks, especially in environments with limited cybersecurity resources or delayed patching cycles. The medium severity rating suggests moderate impact, but the public availability of exploit code could accelerate exploitation attempts. European organizations with interconnected systems or weak network segmentation may face broader exposure. Overall, the threat could disrupt educational services and compromise compliance with data protection regulations.

To mitigate CVE-2026-1551, organizations should first conduct a thorough inventory to identify deployments of itsourcecode School Management System version 1.0. Immediate steps include implementing input validation and sanitization for the 'ID' parameter in the /ramonsys/course/controller.php file to prevent SQL injection. If source code access is available, developers should use parameterized queries or prepared statements to eliminate direct injection risks. Network-level controls such as web application firewalls (WAFs) can provide temporary protection by detecting and blocking malicious SQL payloads targeting the vulnerable endpoint. Organizations should monitor logs for suspicious activity related to the 'ID' parameter and restrict external access to the management system where possible. Regular backups of critical data should be maintained to enable recovery in case of data tampering. Until an official patch is released, consider isolating the affected system or limiting its exposure. Additionally, raising awareness among IT staff about this vulnerability and ensuring timely application of future patches is essential. Coordination with the vendor for patch availability and updates is recommended.
