CVE-2025-13274 identifies a SQL injection vulnerability in Campcodes School Fees Payment Management System version 1.0, specifically in the /ajax.php?action=delete_fees endpoint. The vulnerability arises from improper sanitization of the 'ID' parameter, which is used directly in SQL queries without adequate validation or parameterization. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This can lead to unauthorized data retrieval, modification, or deletion of sensitive school fee payment records. The vulnerability does not require authentication or user interaction, making it easier to exploit. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the attack vector is network-based with low attack complexity but limited impact on confidentiality, integrity, and availability (each rated low). No patches have been officially released yet, and no known exploits are active in the wild, but the public availability of exploit code increases the risk of imminent attacks. The vulnerability affects only version 1.0 of the product, which is used primarily in educational institutions to manage fee payments. The lack of secure coding practices around input handling in this critical financial module highlights the need for immediate remediation to prevent data breaches and service disruptions.

For European organizations, particularly educational institutions using Campcodes School Fees Payment Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive financial data related to student fee payments. Exploitation could lead to unauthorized disclosure of payment records, manipulation of fee data, or denial of service by deleting critical records. This could result in financial losses, reputational damage, regulatory non-compliance (especially under GDPR due to exposure of personal data), and disruption of school administrative operations. The remote and unauthenticated nature of the exploit increases the attack surface, potentially allowing attackers to target multiple institutions simultaneously. Given the critical role of school fee management systems, any compromise could also undermine trust in digital payment processes within the education sector.

Organizations should immediately implement input validation and sanitization on the 'ID' parameter in the /ajax.php?action=delete_fees endpoint to prevent SQL injection. Employing parameterized queries or prepared statements in the database access layer is essential to eliminate injection vectors. Restrict database user permissions to the minimum necessary, avoiding elevated privileges that could exacerbate damage if exploited. Network-level controls such as web application firewalls (WAFs) should be configured to detect and block SQL injection attempts targeting this endpoint. Monitoring and logging access to /ajax.php with suspicious parameters can help detect exploitation attempts early. Since no official patch is currently available, organizations should consider isolating or restricting access to the vulnerable system until remediation is applied. Additionally, conducting a thorough security review of the entire application for similar injection flaws is recommended. Finally, educating staff about the risks and signs of exploitation can improve incident response readiness.
