CVE-2025-13271 identifies a SQL injection vulnerability in version 1.0 of the Campcodes School Fees Payment Management System, specifically in the /ajax.php?action=login endpoint. The vulnerability arises from improper sanitization of the Username parameter, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized disclosure, modification, or deletion of sensitive data such as student records and payment information. The vulnerability is exploitable over the network, increasing the attack surface. Although no public exploit code is currently observed in the wild, the public disclosure heightens the risk of exploitation by threat actors. The CVSS 4.0 vector indicates low complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The lack of a patch or vendor-provided fix at the time of disclosure necessitates immediate mitigation efforts. Given the critical nature of financial and personal data handled by school fee management systems, exploitation could result in significant operational and reputational damage. The vulnerability’s presence in a specialized education payment system suggests targeted attacks against educational institutions or fraud attempts to manipulate payment records.

For European organizations, particularly educational institutions using Campcodes School Fees Payment Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive student and financial data. Exploitation could lead to data breaches involving personally identifiable information (PII), financial fraud, or disruption of fee payment processes, impacting operational continuity. The integrity of payment records could be compromised, resulting in financial losses or erroneous billing. Confidentiality breaches may violate GDPR requirements, exposing organizations to regulatory penalties and reputational harm. Availability impacts could disrupt administrative functions during critical academic periods. The remote, unauthenticated nature of the exploit increases the likelihood of attacks, especially in environments with internet-facing management portals. European institutions with limited cybersecurity resources may be particularly vulnerable to exploitation attempts. The absence of known active exploits currently provides a window for proactive mitigation, but the public disclosure increases the risk of imminent attacks.

1. Immediate code review and remediation of the /ajax.php?action=login endpoint to implement parameterized queries or prepared statements, eliminating direct concatenation of user input into SQL commands. 2. Apply strict input validation and sanitization on the Username parameter to reject malicious payloads. 3. Implement Web Application Firewalls (WAF) with custom rules to detect and block SQL injection attempts targeting the login endpoint. 4. Restrict network access to the management interface hosting the vulnerable system, limiting exposure to trusted IP addresses or internal networks only. 5. Monitor logs for unusual login attempts or SQL error messages indicative of injection attempts. 6. Engage with the vendor for official patches or updates and apply them promptly once available. 7. Conduct security awareness training for IT staff to recognize and respond to exploitation indicators. 8. Regularly back up critical data and test restoration procedures to mitigate impact from potential data corruption or deletion. 9. Consider deploying runtime application self-protection (RASP) solutions to detect and block injection attacks in real-time. 10. Review and enhance overall security posture of educational payment systems, including multi-factor authentication and encryption of sensitive data at rest and in transit.
