CVE-2025-9502 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Loan Management System. The flaw exists in the /ajax.php endpoint, specifically when handling the 'save_payment' action. The vulnerability arises from improper sanitization or validation of the 'loan_id' parameter, allowing an attacker to inject malicious SQL code. This injection can be executed remotely without requiring authentication or user interaction, making it highly accessible to attackers. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The impact on confidentiality, integrity, and availability is limited but present, as the injected SQL commands could allow attackers to read or modify loan payment data or potentially escalate their access within the database. Although no known exploits are currently reported in the wild, the exploit code has been publicly disclosed, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, and no official patches or mitigations have been published at this time. Given the nature of the system—handling sensitive financial loan data—this vulnerability poses a significant risk to data integrity and confidentiality if exploited.

For European organizations using Campcodes Online Loan Management System 1.0, this vulnerability could lead to unauthorized access to sensitive financial data, including loan payment records and client information. Exploitation could result in data breaches, financial fraud, or manipulation of loan records, undermining trust and compliance with data protection regulations such as GDPR. The remote, unauthenticated nature of the attack vector increases the likelihood of exploitation, potentially leading to operational disruptions or reputational damage. Financial institutions and loan management entities in Europe relying on this system may face regulatory scrutiny and financial penalties if customer data is compromised. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within the affected organizations.

Organizations should immediately audit their usage of Campcodes Online Loan Management System and identify any instances of version 1.0 in their environment. Since no official patch is currently available, the following specific mitigations are recommended: 1) Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the 'loan_id' parameter in /ajax.php?action=save_payment. 2) Apply input validation and parameterized queries or prepared statements at the application level if source code access is available, ensuring all inputs are sanitized before database queries. 3) Restrict access to the vulnerable endpoint by IP whitelisting or VPN access to reduce exposure. 4) Monitor logs for unusual or suspicious activity related to the 'save_payment' action, focusing on anomalous parameter values or repeated requests. 5) Plan for an upgrade or replacement of the vulnerable system version once a patch or newer secure version is released by the vendor. 6) Conduct regular security assessments and penetration tests to detect similar injection flaws in other parts of the application.
