CVE-2025-9744 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Loan Management System, specifically within the /ajax.php endpoint when the 'action' parameter is set to 'login'. The vulnerability arises from improper sanitization or validation of the 'Username' parameter, allowing an attacker to inject malicious SQL code. This injection can be executed remotely without any authentication or user interaction, making it a highly accessible attack vector. The vulnerability could allow attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of service. The CVSS 4.0 score of 6.9 classifies this as a medium severity issue, reflecting the ease of exploitation (no privileges or user interaction required) but limited scope or impact on confidentiality, integrity, and availability (each rated low). Although no public exploits are currently known in the wild, proof-of-concept code has been made publicly available, increasing the risk of exploitation. The lack of available patches or mitigations from the vendor further exacerbates the threat. Given that the affected system is an online loan management platform, the data at risk likely includes sensitive financial and personal information, which could have serious privacy and regulatory implications if compromised.

For European organizations using the Campcodes Online Loan Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive customer financial data. Exploitation could lead to unauthorized disclosure of personal loan information, financial records, and potentially allow attackers to alter loan data or disrupt loan processing services. This could result in financial fraud, reputational damage, and non-compliance with stringent European data protection regulations such as GDPR. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially if the system is internet-facing. Additionally, disruption of loan management services could impact business continuity and customer trust. Organizations in the financial sector are often targeted by cybercriminals, so this vulnerability could be leveraged as part of broader attacks or fraud schemes. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional chained exploits, but the risk to sensitive data remains substantial.

Immediate mitigation steps should include implementing strong input validation and parameterized queries or prepared statements in the /ajax.php?action=login endpoint to prevent SQL injection. Since no official patch is currently available, organizations should consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'Username' parameter. Network segmentation and restricting access to the loan management system to trusted IP ranges can reduce exposure. Regularly monitoring logs for suspicious activity related to login attempts and unusual database queries is critical. Organizations should also conduct thorough code reviews and security testing of the affected application components. If feasible, migrating to a newer, patched version of the software or an alternative solution should be prioritized. Additionally, encrypting sensitive data at rest and in transit can mitigate the impact of potential data breaches. Finally, organizations must ensure compliance with GDPR by having incident response plans ready to address potential data breaches stemming from this vulnerability.
