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 insufficient sanitization and validation of the 'ID' parameter, which is directly used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. The vulnerability does not require authentication or user interaction, increasing its risk profile. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the ease of exploitation (network attack vector, low attack complexity) but limited impact scope (partial confidentiality, integrity, and availability impacts). The system’s lack of secure coding practices in this module exposes sensitive financial data related to school fee payments, which could be extracted, altered, or deleted. Although no active exploitation has been confirmed, the public availability of the exploit code raises the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been released yet. The attack surface is primarily remote web access to the vulnerable endpoint, making it accessible to external threat actors. The lack of authentication requirement further exacerbates the risk, allowing unauthenticated attackers to exploit the flaw. This vulnerability highlights the critical need for secure input handling and database query parameterization in web applications managing sensitive financial data.

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 financial data related to school fees. Exploitation could lead to unauthorized disclosure of sensitive payment information, manipulation or deletion of payment records, and potential disruption of fee management services. This could result in financial losses, reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and operational downtime. Given the critical nature of educational financial systems, any disruption could impact student services and institutional trust. The medium severity rating suggests that while the vulnerability is exploitable remotely without authentication, the overall impact is somewhat limited by the scope of affected functionality. However, the public availability of exploit code increases the urgency for European organizations to address this issue promptly. The lack of patches means organizations must rely on mitigation strategies to reduce exposure. The impact is amplified in environments where network segmentation and web application firewalls are not adequately implemented.

1. Immediately implement input validation and sanitization on the 'ID' parameter in the /ajax.php?action=delete_fees endpoint to prevent injection of malicious SQL code. 2. Refactor the application code to use parameterized queries or prepared statements for all database interactions to eliminate direct concatenation of user input into SQL commands. 3. Restrict database user privileges to the minimum necessary, preventing unauthorized data modification or deletion even if injection occurs. 4. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. 5. Monitor web server and application logs for suspicious activity related to the vulnerable endpoint, including unusual parameter values or repeated access attempts. 6. If possible, isolate the payment management system within a segmented network zone to limit exposure to external threats. 7. Engage with the vendor (Campcodes) for official patches or updates and apply them promptly once available. 8. Educate IT and security teams about this vulnerability and ensure incident response plans include steps for SQL injection attacks. 9. Conduct regular security assessments and code reviews focusing on input handling and database interactions in the payment system. 10. Consider temporary disabling or restricting access to the vulnerable functionality if immediate patching is not feasible.
