CVE-2025-13274 identifies a SQL injection vulnerability in Campcodes School Fees Payment Management System version 1.0. The vulnerability resides in the /ajax.php endpoint when called with the action parameter set to 'delete_fees'. Specifically, the 'ID' argument is not properly sanitized or validated, allowing an attacker to inject arbitrary SQL code. This injection flaw can be exploited remotely without requiring authentication or user interaction, making it easier for attackers to leverage. The vulnerability could allow attackers to execute unauthorized SQL queries against the backend database, potentially leading to unauthorized data disclosure, data manipulation, or deletion. The CVSS 4.0 base score is 5.3 (medium), reflecting the network attack vector, low complexity, no privileges required, and no user interaction needed, but limited scope and impact on confidentiality, integrity, and availability. Although no active exploits in the wild have been reported, a public exploit is available, increasing the likelihood of exploitation. The affected product is primarily used in educational institutions for managing school fee payments, making the data sensitive and critical for operational continuity. No official patches or updates have been linked yet, so mitigation relies on input validation, web application firewalls, and monitoring.

The SQL injection vulnerability in Campcodes School Fees Payment Management System can have significant impacts on organizations, especially educational institutions relying on this software for financial transactions. Successful exploitation could lead to unauthorized access to sensitive student and payment data, including personal information and financial records, compromising confidentiality. Attackers could alter or delete payment records, impacting data integrity and potentially causing financial discrepancies or loss of trust. Availability could also be affected if attackers execute destructive SQL commands or cause database corruption, disrupting payment processing operations. Given the remote and unauthenticated nature of the exploit, attackers can easily target vulnerable systems over the internet, increasing the risk of widespread attacks. The availability of a public exploit further raises the threat level, as less skilled attackers can attempt exploitation. Organizations may face regulatory and reputational consequences if sensitive data is exposed or manipulated. The impact is particularly critical in countries with large deployments of this system or where educational institutions have limited cybersecurity resources.

To mitigate CVE-2025-13274, organizations should implement multiple layers of defense. First, apply any available patches or updates from Campcodes as soon as they are released. In the absence of official patches, immediate steps include implementing strict input validation and sanitization on the 'ID' parameter in /ajax.php?action=delete_fees to prevent injection of malicious SQL code. Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user inputs into SQL commands. Deploy a Web Application Firewall (WAF) configured to detect and block SQL injection patterns targeting this endpoint. Conduct thorough security testing and code review to identify and remediate similar injection points. Monitor logs for unusual database query patterns or repeated requests to the vulnerable endpoint. Restrict network access to the management system to trusted IP addresses where feasible. Educate administrators and developers about secure coding practices and the risks of SQL injection. Finally, maintain regular backups of the database to enable recovery in case of data corruption or deletion.
