CVE-2025-13269 identifies a SQL injection vulnerability in Campcodes School Fees Payment Management System version 1.0, specifically in the /ajax.php?action=save_payment endpoint. The vulnerability arises from improper sanitization of the 'ID' parameter, which is directly used in SQL queries without adequate validation or parameterization. An attacker with low privileges (PR:L) can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the underlying database. The vulnerability does not require user interaction (UI:N) and can be exploited over the network (AV:N). The CVSS 4.0 vector indicates partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L), reflecting that the attacker can cause limited but meaningful damage. Although no public exploits are currently known in the wild, the public disclosure increases the likelihood of exploitation attempts. The lack of vendor patches at the time of disclosure necessitates immediate mitigation efforts by affected organizations. This vulnerability poses a significant risk to the integrity of financial data and personal information managed by the system, which is critical for school fee management operations.

For European organizations, particularly educational institutions using Campcodes School Fees Payment Management System 1.0, this vulnerability could lead to unauthorized data access, manipulation of payment records, and potential disruption of fee payment processes. Confidentiality breaches may expose sensitive student and financial data, leading to privacy violations under GDPR. Integrity compromises could result in fraudulent payment records or financial discrepancies, affecting trust and operational accuracy. Availability impacts, while limited, could disrupt payment processing temporarily. The medium severity rating reflects that while the attack requires some privilege, the remote exploitability and lack of user interaction increase risk. Organizations in Europe must consider the regulatory and reputational consequences of such data breaches, especially given the sensitivity of educational financial data.

1. Apply vendor-provided patches immediately once available to address the SQL injection vulnerability. 2. In the absence of patches, implement strict input validation on the 'ID' parameter, ensuring it only accepts expected numeric or alphanumeric values. 3. Refactor the codebase to use parameterized queries or prepared statements to prevent SQL injection. 4. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the /ajax.php?action=save_payment endpoint. 5. Conduct regular security audits and code reviews focusing on input handling in payment-related modules. 6. Monitor database logs and application logs for unusual queries or access patterns indicative of exploitation attempts. 7. Educate developers and administrators on secure coding practices and the importance of sanitizing user inputs. 8. Restrict access to the payment management system to trusted networks or VPNs where feasible to reduce exposure. 9. Maintain up-to-date backups of payment data to enable recovery in case of data corruption or loss.
