CVE-2025-13270 identifies a SQL injection vulnerability in Campcodes School Fees Payment Management System version 1.0, specifically in the /ajax.php?action=save_course endpoint. The vulnerability arises from improper sanitization of the 'ID' parameter, which an attacker can manipulate to inject arbitrary SQL commands. This injection flaw allows remote attackers to execute unauthorized queries on the backend database without requiring user interaction or elevated privileges beyond low-level access. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the attack vector is network-based, with low complexity and no user interaction needed, but requiring some privileges. The vulnerability could enable attackers to read, modify, or delete sensitive data such as student records and payment information, potentially leading to data breaches, financial fraud, or denial of service. Although no exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of future exploitation. The affected product is primarily used in educational institutions for managing school fee payments, making the confidentiality and integrity of financial and personal data critical. The lack of vendor patches at the time of publication necessitates immediate defensive measures to mitigate risk.

For European organizations, particularly educational institutions using the Campcodes School Fees Payment Management System, this vulnerability could result in unauthorized access to sensitive student and financial data, leading to privacy violations and regulatory non-compliance under GDPR. Attackers exploiting this flaw could manipulate payment records, causing financial discrepancies or fraud. The integrity of academic and financial data could be compromised, undermining trust in the institution’s systems. Additionally, disruption of payment processing services could impact operational availability, affecting students and staff. Given the critical nature of educational data and the increasing digitization of school administration in Europe, the impact extends beyond immediate financial loss to reputational damage and potential legal consequences. Organizations without robust network segmentation or monitoring may be more vulnerable to exploitation. The medium severity score suggests a moderate but tangible risk that requires prompt attention to avoid escalation.

1. Apply vendor patches immediately once released to address the SQL injection vulnerability in the /ajax.php?action=save_course endpoint. 2. Until patches are available, implement web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'ID' parameter. 3. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters used in database queries. 4. Restrict database user permissions to the minimum necessary, avoiding use of high-privilege accounts for application database access. 5. Monitor application logs and network traffic for unusual query patterns or repeated failed attempts indicative of injection attacks. 6. Segment the school fees payment system network from other critical infrastructure to limit lateral movement in case of compromise. 7. Educate IT staff and administrators on the vulnerability and encourage prompt incident reporting and response. 8. Consider implementing parameterized queries or prepared statements in the application code to prevent injection flaws. 9. Perform regular security assessments and penetration testing focused on injection vulnerabilities. 10. Backup critical data regularly and verify restoration procedures to mitigate impact of potential data corruption or deletion.
