CVE-2025-9744 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Loan Management System. The vulnerability exists in the /ajax.php endpoint when accessed with the action=login parameter. Specifically, the Username argument is improperly sanitized, allowing an attacker to inject malicious SQL code. This flaw can be exploited remotely without any authentication or user interaction, making it highly accessible to attackers. The injection can lead to unauthorized access to the backend database, potentially exposing sensitive customer data such as personal identification, loan details, and financial information. Furthermore, the attacker could manipulate or delete data, impacting the integrity and availability of the system. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, no privileges or user interaction required, but limited confidentiality, integrity, and availability impacts. Although no public exploits are currently known in the wild, the exploit code has been made publicly available, increasing the risk of exploitation by opportunistic attackers. Since the vulnerability affects a core login function, it poses a critical risk to the authentication process and overall system security. The lack of a patch or mitigation guidance from the vendor increases the urgency for organizations to implement compensating controls.

For European organizations using the Campcodes Online Loan Management System, this vulnerability could lead to significant data breaches involving sensitive financial and personal customer information. The compromise of loan management data could result in financial fraud, identity theft, and regulatory non-compliance, particularly under GDPR requirements for protecting personal data. The integrity of loan records could be undermined, causing operational disruptions and loss of customer trust. Availability impacts may arise if attackers delete or corrupt database records, potentially halting loan processing services. Given the remote and unauthenticated nature of the exploit, attackers can easily target exposed systems, increasing the likelihood of attacks. Financial institutions and loan service providers in Europe are especially at risk, as they handle large volumes of sensitive data and are subject to strict regulatory oversight. A successful attack could also lead to reputational damage and significant remediation costs.

1. Immediate mitigation should include implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting the /ajax.php?action=login endpoint, specifically filtering suspicious payloads in the Username parameter. 2. Conduct a thorough code review and apply proper input validation and parameterized queries or prepared statements to sanitize all user inputs, especially the Username field. 3. Restrict direct internet access to the loan management system where possible, limiting exposure to trusted internal networks or VPNs. 4. Monitor logs for unusual database queries or repeated failed login attempts indicative of injection attempts. 5. If a patch from the vendor becomes available, prioritize its immediate deployment. 6. Implement database-level protections such as least privilege access for the application user to minimize damage from potential injection attacks. 7. Perform regular security assessments and penetration testing focused on injection vulnerabilities. 8. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases.
