CVE-2025-13270 identifies a SQL injection vulnerability in the 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 is directly used in SQL queries without adequate validation or parameterization. This allows an attacker to craft malicious input that alters the intended SQL command, potentially enabling unauthorized data retrieval, modification, or deletion within the backend database. The attack vector is remote and does not require authentication or user interaction, increasing the risk of exploitation. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no exploits are currently observed in the wild, the public disclosure of the exploit code increases the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been released yet. This flaw is critical for organizations relying on this system for managing school fee payments, as it could lead to data breaches or financial fraud.

For European organizations, particularly educational institutions using Campcodes School Fees Payment Management System 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive student and financial data, compromising confidentiality. Integrity of payment records and course information could be altered, potentially causing financial discrepancies or administrative errors. Availability of the payment system might be disrupted if attackers execute destructive SQL commands. The impact extends to reputational damage and regulatory non-compliance, especially under GDPR, due to exposure of personal data. The remote and unauthenticated nature of the attack vector increases the threat level, as attackers can exploit the vulnerability without insider access or user involvement. This could facilitate broader attacks such as data exfiltration, fraud, or ransomware deployment if combined with other vulnerabilities.

To mitigate CVE-2025-13270, organizations should immediately implement input validation and sanitization on the 'ID' parameter in the /ajax.php?action=save_course endpoint. Employing parameterized queries or prepared statements is critical to prevent SQL injection. Until an official patch is released, consider deploying a Web Application Firewall (WAF) with custom rules to detect and block SQL injection payloads targeting this endpoint. Restrict network access to the application backend to trusted IP addresses where feasible. Conduct thorough code reviews and security testing of the payment system to identify and remediate similar vulnerabilities. Regularly monitor logs for suspicious activity related to SQL injection attempts. Educate IT staff and administrators about this vulnerability and ensure incident response plans include steps for SQL injection attacks. Finally, engage with the vendor for timely patch releases and updates.
