CVE-2025-9504 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Loan Management System. The vulnerability resides in the /ajax.php endpoint, specifically when handling the 'action=save_plan' request parameter. The issue arises due to improper sanitization or validation of the 'ID' argument, which allows an attacker to inject malicious SQL code. This injection flaw can be exploited 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 attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), suggesting that while the vulnerability can be exploited to extract or manipulate some data, it may not lead to full system compromise or widespread disruption. No patches or fixes have been published yet, and there are no known exploits in the wild at the time of reporting. However, the exploit code is publicly available, increasing the risk of exploitation by opportunistic attackers. The vulnerability affects only version 1.0 of the Campcodes Online Loan Management System, a product used for managing online loan operations, which likely involves sensitive financial and personal data. The SQL Injection flaw could allow attackers to access or modify loan plans, user data, or other backend database information, potentially leading to data breaches or fraudulent activities.

For European organizations using Campcodes Online Loan Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive financial data. Exploitation could lead to unauthorized disclosure of customer loan information, manipulation of loan plans, or unauthorized financial transactions. This could result in regulatory non-compliance under GDPR due to exposure of personal data, financial losses, reputational damage, and erosion of customer trust. Although the impact on availability is limited, the integrity and confidentiality risks are substantial given the nature of the data handled by loan management systems. Financial institutions and lending companies in Europe relying on this software could face targeted attacks aiming to exploit this vulnerability for financial gain or data theft. The remote and unauthenticated nature of the exploit increases the threat level, especially if the system is exposed to the internet without adequate network protections.

1. Immediate mitigation should include restricting external access to the /ajax.php endpoint, especially the 'save_plan' action, through network-level controls such as firewalls or web application firewalls (WAFs) configured to detect and block SQL injection patterns. 2. Implement input validation and parameterized queries or prepared statements in the application code to sanitize the 'ID' parameter and prevent injection attacks. 3. If possible, upgrade to a patched version of the Campcodes Online Loan Management System once available; until then, consider disabling or limiting the vulnerable functionality. 4. Conduct thorough security assessments and penetration testing on the loan management system to identify and remediate any other injection or input validation vulnerabilities. 5. Monitor logs and network traffic for unusual database queries or suspicious activity targeting the vulnerable endpoint. 6. Educate IT and security teams on the risks associated with SQL injection and ensure incident response plans are updated to handle potential exploitation. 7. Consider deploying database activity monitoring tools to detect and alert on anomalous queries indicative of injection attempts.
