CVE-2025-9678 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Loan Management System. The vulnerability exists in an unspecified function within the /ajax.php endpoint, specifically when the 'action' parameter is set to 'delete_borrower' and the 'ID' argument is manipulated. This improper input validation allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. The vulnerability enables an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access, data modification, or deletion. The CVSS 4.0 base score is 6.9 (medium severity), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and has partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit code is publicly available, increasing the risk of exploitation, although no active exploitation in the wild has been reported yet. The lack of a patch or mitigation guidance from the vendor increases the urgency for organizations to implement compensating controls. This vulnerability is critical for systems managing sensitive financial and personal data, as loan management systems typically store borrower information, loan details, and transaction records.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive customer financial data and personal information. Exploitation could lead to unauthorized disclosure of borrower identities, loan terms, and payment histories, potentially violating GDPR and other data protection regulations. Integrity compromise could allow attackers to alter loan records, causing financial discrepancies, fraud, or disruption of loan servicing operations. Availability impacts, while partial, could disrupt loan management processes, affecting customer service and operational continuity. Financial institutions, credit unions, and fintech companies using the affected Campcodes system could face reputational damage, regulatory penalties, and financial losses. The public availability of exploit code increases the likelihood of opportunistic attacks, especially targeting organizations that have not applied mitigations or are unaware of the vulnerability.

Given the absence of an official patch, European organizations should immediately implement input validation and sanitization controls on the 'ID' parameter in the /ajax.php?action=delete_borrower endpoint to prevent SQL injection. Employing prepared statements or parameterized queries in the application code is critical. Organizations should also deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting this endpoint. Conduct thorough code reviews and penetration testing focused on injection flaws in all user-supplied inputs. Monitoring and logging database queries and application logs for anomalous patterns indicative of SQL injection attempts is recommended. Restrict database user permissions to the minimum necessary to limit the impact of any successful injection. Additionally, organizations should isolate the loan management system within segmented network zones to reduce exposure. Finally, maintain awareness of vendor updates for official patches and apply them promptly once available.
