CVE-2026-2018 identifies a SQL injection vulnerability in the itsourcecode School Management System version 1.0, specifically within the /ramonsys/settings/controller.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which an attacker can manipulate to inject malicious SQL queries. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:N). The vulnerability impacts the confidentiality, integrity, and availability of the system by potentially exposing sensitive student and administrative data, modifying records, or causing denial of service through database corruption or resource exhaustion. The CVSS score of 6.9 (medium severity) reflects the ease of exploitation combined with limited scope and impact. Although no active exploitation has been reported, the public availability of exploit code increases the likelihood of attacks. The affected product is a school management system, which typically manages critical educational data, making this vulnerability particularly concerning for educational institutions. The lack of patches at the time of reporting necessitates immediate defensive measures to prevent exploitation.

For European organizations, particularly educational institutions using the itsourcecode School Management System 1.0, this vulnerability poses a significant risk to sensitive student and staff data confidentiality and integrity. Successful exploitation could lead to unauthorized disclosure of personal information, alteration of academic records, or disruption of school operations. This could result in regulatory non-compliance with GDPR due to data breaches, reputational damage, and operational downtime. The remote and unauthenticated nature of the attack vector increases the threat level, as attackers can exploit the vulnerability without insider access or user interaction. The impact extends beyond individual schools to potentially affect regional educational authorities if centralized management systems are compromised. Additionally, the exposure of educational data could have broader societal implications, including identity theft or targeted attacks on vulnerable populations.

Organizations should immediately audit their deployment of the itsourcecode School Management System to identify affected versions (1.0). Until an official patch is released, implement strict input validation and sanitization on all parameters, especially the 'ID' parameter in /ramonsys/settings/controller.php, to block malicious SQL payloads. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. Restrict network access to the management interface by IP whitelisting or VPN to reduce exposure. Conduct thorough logging and monitoring for unusual database queries or application behavior indicative of exploitation attempts. Educate administrators on the vulnerability and ensure backups of critical data are current to enable recovery in case of compromise. Engage with the vendor for timely patch releases and apply updates promptly once available. Consider isolating the affected system within segmented network zones to limit lateral movement if exploited.
