CVE-2025-13269 identifies a SQL injection vulnerability in Campcodes School Fees Payment Management System version 1.0, specifically within the /ajax.php?action=save_payment endpoint. The vulnerability arises from insufficient input validation on the 'ID' parameter, which is directly used in SQL queries without proper sanitization or parameterization. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially enabling unauthorized data access, modification, or deletion within the backend database. The vulnerability does not require user interaction and can be exploited over the network, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates that exploitation requires low complexity and low privileges but no authentication, with partial impact on confidentiality, integrity, and availability. Although no known exploits have been reported in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The affected product is primarily used in educational institutions for managing school fee payments, making sensitive financial and personal data at risk. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts by administrators. This vulnerability exemplifies common risks associated with web applications that fail to properly sanitize user inputs, emphasizing the need for secure coding practices such as prepared statements and input validation.

For European organizations, particularly educational institutions using Campcodes School Fees Payment Management System 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of sensitive financial and student data. Exploitation could lead to unauthorized disclosure of payment information, manipulation of payment records, or denial of service by corrupting database contents. This could result in financial losses, reputational damage, regulatory penalties under GDPR due to data breaches, and disruption of critical school administrative functions. The remote and unauthenticated nature of the exploit increases the attack surface, potentially allowing attackers to target multiple institutions across Europe. The partial impact on data confidentiality and integrity could facilitate fraud or identity theft. Given the critical role of payment systems in educational settings, any disruption or data compromise could have cascading effects on operational continuity and stakeholder trust.

To mitigate CVE-2025-13269, organizations should immediately implement input validation and sanitization on the 'ID' parameter within the /ajax.php?action=save_payment endpoint. The preferred approach is to refactor the code to use parameterized queries or prepared statements to eliminate SQL injection risks. In the absence of an official patch, administrators should consider deploying web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this endpoint. Network segmentation can limit exposure of the payment system to trusted internal networks only. Regular monitoring of database logs and web server logs for suspicious queries or anomalies is recommended to detect exploitation attempts early. Additionally, organizations should conduct security audits and penetration testing focused on input validation controls. Backup and recovery procedures must be verified to ensure rapid restoration in case of data corruption. Finally, coordinate with Campcodes for timely patch releases and apply updates as soon as they become available.
