CVE-2026-2073 identifies a SQL injection vulnerability in itsourcecode School Management System version 1.0, specifically within an unknown function in the /ramonsys/user/index.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which can be manipulated remotely without authentication or user interaction to inject arbitrary SQL commands. This allows attackers to execute unauthorized database queries, potentially leading to data leakage, unauthorized data modification, or deletion. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity, with network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the public disclosure increases the likelihood of exploitation attempts. The affected software is used in educational environments, where sensitive student and staff data may be stored, making the impact significant if exploited. The lack of available patches necessitates immediate attention to input validation and deployment of compensating controls to reduce risk.

For European organizations, particularly educational institutions using the itsourcecode School Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive student and staff data, including personal information and academic records. Exploitation could lead to data breaches, loss of data integrity, and potential disruption of school management operations. The impact extends to reputational damage, regulatory non-compliance (e.g., GDPR violations), and potential financial penalties. Since the vulnerability can be exploited remotely without authentication, attackers could leverage it to gain persistent access or pivot to other internal systems. The medium severity indicates a moderate but tangible risk, especially in environments where this software is critical to daily operations and data management.

1. Conduct a thorough code review of the /ramonsys/user/index.php file to identify and remediate the SQL injection vulnerability by implementing proper input validation and parameterized queries or prepared statements for all database interactions involving the 'ID' parameter. 2. If source code modification is not immediately feasible, deploy web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the vulnerable parameter. 3. Restrict network access to the affected application to trusted IP ranges where possible, reducing exposure to external attackers. 4. Implement continuous monitoring and logging of database queries and web application traffic to detect anomalous activities indicative of exploitation attempts. 5. Educate system administrators and security teams about the vulnerability and ensure timely application of any future patches or updates released by the vendor. 6. Perform regular security assessments and penetration testing focused on injection flaws to proactively identify and mitigate similar vulnerabilities.
