CVE-2025-13273 is a SQL injection vulnerability identified in Campcodes School Fees Payment Management System version 1.0. The vulnerability resides in the /ajax.php endpoint when the action parameter is set to delete_payment. Specifically, the ID argument is not properly sanitized, allowing an attacker to inject arbitrary SQL commands remotely. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized data retrieval, modification, or deletion. The vulnerability requires low privileges (PR:L), no user interaction (UI:N), and can be exploited over the network (AV:N). The impact on confidentiality, integrity, and availability is limited but present (VC:L, VI:L, VA:L). The CVSS 4.0 base score is 5.3, indicating a medium severity level. Although no exploits have been observed in the wild, the public release of exploit code increases the likelihood of attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been published yet. The Campcodes system is used primarily by educational institutions to manage school fee payments, making the data sensitive and critical for operational continuity. Attackers exploiting this vulnerability could gain unauthorized access to payment records, manipulate financial data, or disrupt payment processing services.

The SQL injection vulnerability in Campcodes School Fees Payment Management System can have several impacts on affected organizations. Confidentiality may be compromised as attackers could extract sensitive payment and student data from the backend database. Integrity risks include unauthorized modification or deletion of payment records, potentially causing financial discrepancies or fraud. Availability could be affected if attackers execute destructive queries or cause database errors, disrupting the payment management service. Educational institutions rely on accurate and secure fee management for operational and financial stability; thus, exploitation could lead to financial loss, reputational damage, and regulatory compliance issues related to data protection. The medium severity score reflects that while the vulnerability is exploitable remotely without user interaction, it requires some level of privilege and has limited scope in impact. However, the public availability of exploit code increases the risk of widespread attacks, especially targeting institutions that have not applied mitigations. The impact is more pronounced in regions where Campcodes software is widely used or where educational institutions have limited cybersecurity resources.

To mitigate CVE-2025-13273, organizations should first verify if they are running Campcodes School Fees Payment Management System version 1.0 and restrict access to the /ajax.php?action=delete_payment endpoint. Since no official patches are currently available, immediate mitigations include implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting the ID parameter. Input validation and parameterized queries should be enforced in the application code to sanitize and safely handle user inputs. Network segmentation and access controls should limit exposure of the management system to trusted internal networks only. Regular monitoring of logs for suspicious database queries or repeated access attempts to the vulnerable endpoint can help detect exploitation attempts early. Organizations should also plan to upgrade to a patched version once available or consider alternative secure payment management solutions. Additionally, conducting security awareness training for administrators and applying the principle of least privilege to user accounts can reduce the risk of exploitation.
