CVE-2025-13057 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 save_student. Specifically, the ID parameter is improperly sanitized, allowing an attacker to inject arbitrary SQL commands. This injection flaw can be exploited remotely without requiring authentication or user interaction, making it relatively easy to exploit. The vulnerability could allow attackers to read, modify, or delete sensitive student or payment data stored in the backend database. The CVSS 4.0 base score is 5.3, reflecting a medium severity due to the lack of privilege requirements but limited scope and impact. No patches or fixes have been officially released by the vendor yet, and no active exploitation has been reported, though a public exploit exists. This vulnerability highlights the importance of input validation and parameterized queries in web applications handling sensitive financial and personal data. Organizations using this system should monitor for updates and consider immediate mitigations to prevent exploitation.

The SQL injection vulnerability could lead to unauthorized disclosure, modification, or deletion of sensitive student and payment information, potentially violating privacy regulations and damaging organizational reputation. Attackers could manipulate payment records, disrupt fee processing, or gain further access to internal systems if the database contains credentials or other sensitive data. The remote, unauthenticated nature of the exploit increases the risk of widespread attacks, especially in educational institutions relying on this system for fee management. Data integrity and availability could be compromised, leading to financial discrepancies and operational disruptions. Although currently no active exploitation is reported, the availability of a public exploit increases the likelihood of future attacks. Organizations worldwide using Campcodes School Fees Payment Management System 1.0 are at risk, particularly those with limited cybersecurity defenses or delayed patch management processes.

Organizations should immediately audit their use of Campcodes School Fees Payment Management System version 1.0 and restrict access to the /ajax.php?action=save_student endpoint through network controls such as web application firewalls (WAFs) that can detect and block SQL injection payloads. Implement input validation and parameterized queries in the application code to sanitize the ID parameter and other user inputs. If possible, isolate the payment management system within a segmented network zone with strict access controls to limit exposure. Monitor logs for suspicious activity targeting the vulnerable endpoint. Engage with the vendor for official patches or updates and apply them promptly once available. As a temporary measure, disable or restrict the vulnerable functionality if feasible. Conduct regular security assessments and penetration testing focused on injection flaws. Educate developers on secure coding practices to prevent similar vulnerabilities in future releases.
