CVE-2025-13555 identifies a SQL injection vulnerability in version 1.0 of the Campcodes School File Management System, specifically within the login component's /index.php file. The vulnerability arises from improper sanitization of the stud_no parameter, which can be manipulated remotely without authentication or user interaction to inject malicious SQL queries. This flaw allows attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data retrieval, modification, or deletion. The CVSS 4.0 base score is 6.9 (medium), reflecting network attack vector, low attack complexity, no privileges or user interaction required, and partial impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, a public exploit is available, increasing the risk of attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The lack of secure coding practices in input validation and parameterized queries is the root cause. This vulnerability is critical for environments managing sensitive student data, as it can lead to data breaches or operational disruption.

For European organizations, particularly educational institutions using Campcodes School File Management System 1.0, this vulnerability poses a significant risk of unauthorized access to sensitive student records and administrative data. Exploitation can result in data leakage, data tampering, or denial of service, undermining confidentiality, integrity, and availability of critical educational data. Given the remote and unauthenticated nature of the attack, threat actors can easily target vulnerable systems over the internet. This can lead to reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. The medium severity score indicates a moderate but tangible risk, especially in environments lacking compensating controls. The presence of a public exploit increases the likelihood of opportunistic attacks. Organizations may also face challenges in incident response and recovery if backups or monitoring are insufficient. Overall, the vulnerability threatens data privacy and system reliability in European educational sectors.

Immediate mitigation should focus on applying vendor-provided patches once available. In the absence of official patches, organizations should implement strict input validation on the stud_no parameter, ensuring only expected numeric or alphanumeric formats are accepted. Employing parameterized SQL queries or prepared statements can prevent injection attacks by separating code from data. Web application firewalls (WAFs) can be configured to detect and block SQL injection patterns targeting the vulnerable endpoint. Regular security audits and code reviews should be conducted to identify similar vulnerabilities. Network segmentation and limiting external access to the management system can reduce exposure. Monitoring logs for unusual database queries or repeated failed login attempts can help detect exploitation attempts early. Lastly, organizations should maintain up-to-date backups and have an incident response plan tailored to data breach scenarios involving educational data.
