CVE-2026-1590 is a SQL injection vulnerability identified in itsourcecode School Management System version 1.0. The flaw exists in the /ramonsys/faculty/index.php file, where the ID parameter is improperly sanitized, allowing attackers to inject arbitrary SQL commands. This vulnerability can be exploited remotely without requiring any authentication or user interaction, making it accessible to a wide range of attackers. The injection can lead to unauthorized data access, modification, or deletion, impacting the confidentiality, integrity, and availability of the system's database. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity, with the vector highlighting network attack vector, low attack complexity, no privileges or user interaction required, and low impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, a public exploit is available, increasing the likelihood of future attacks. The affected product is primarily used in educational environments, which often contain sensitive student and faculty data, making this vulnerability a significant concern for educational institutions. The lack of available patches at the time of reporting necessitates immediate mitigation through secure coding practices and monitoring. The vulnerability's presence in a school management system underscores the importance of securing educational IT infrastructure against injection attacks.

For European organizations, particularly educational institutions using itsourcecode School Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive student and faculty information, including personal data and academic records. Exploitation could lead to data breaches, data manipulation, or denial of service conditions impacting school operations. Given the remote and unauthenticated nature of the attack, threat actors could leverage this vulnerability to gain footholds in educational networks, potentially using them as pivot points for broader attacks. The impact extends beyond data loss to reputational damage, regulatory non-compliance (e.g., GDPR violations), and operational disruption. Since school management systems are critical for daily administrative functions, exploitation could disrupt educational services. The medium severity rating reflects moderate risk but should not be underestimated due to the sensitive nature of the data involved and the ease of exploitation.

1. Apply official patches or updates from itsourcecode as soon as they become available to address the SQL injection vulnerability directly. 2. In the absence of patches, implement immediate input validation and sanitization on the ID parameter in /ramonsys/faculty/index.php to prevent injection of malicious SQL code. 3. Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user input into SQL commands. 4. Conduct thorough code reviews and security testing of the affected module and other parts of the application to identify and remediate similar injection flaws. 5. Monitor database logs and application logs for unusual queries or access patterns indicative of exploitation attempts. 6. Restrict database user privileges to the minimum necessary to limit the impact of a successful injection attack. 7. Educate IT staff and administrators about the vulnerability and signs of exploitation to enable rapid detection and response. 8. Consider network-level protections such as web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the vulnerable endpoint. 9. Regularly back up critical data and verify restoration procedures to minimize operational impact in case of data compromise.
