CVE-2025-9506 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, specifically when handling the 'delete_plan' action parameter. An attacker can manipulate the 'ID' argument in the request to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database without any user interaction or privileges. The vulnerability arises due to insufficient input validation and improper sanitization of user-supplied input before it is incorporated into SQL queries. Exploiting this flaw could enable attackers to read, modify, or delete sensitive loan management data, potentially compromising the confidentiality, integrity, and availability of the system's database. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is rated as low individually but combined can lead to significant damage. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. No patches or mitigations have been officially released by the vendor at this time, emphasizing the need for immediate defensive measures by affected organizations.

For European organizations using the Campcodes Online Loan Management System 1.0, this vulnerability poses a significant risk to sensitive financial data and loan management operations. Successful exploitation could lead to unauthorized disclosure of customer loan details, manipulation or deletion of loan plans, and disruption of loan processing services. This could result in financial losses, regulatory non-compliance (e.g., GDPR violations due to data breaches), reputational damage, and operational downtime. Given the financial sector's critical nature and strict regulatory environment in Europe, such an incident could trigger investigations and fines. Additionally, attackers could leverage the compromised system as a foothold for further lateral movement within the organization's network, potentially escalating the impact. The remote and unauthenticated nature of the attack vector increases the threat level, as attackers do not need insider access or user credentials to exploit the vulnerability.

1. Immediate mitigation should include implementing a Web Application Firewall (WAF) with rules specifically designed to detect and block SQL injection attempts targeting the /ajax.php?action=delete_plan endpoint. 2. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize the 'ID' parameter and any other user inputs interacting with the database. 3. If possible, restrict access to the vulnerable endpoint by IP whitelisting or network segmentation to limit exposure. 4. Monitor logs for unusual or suspicious requests targeting the vulnerable endpoint to detect potential exploitation attempts early. 5. Engage with the vendor or development team to obtain or develop an official patch or upgrade to a fixed version of the software. 6. Perform a comprehensive security assessment of the entire loan management system to identify and remediate other potential vulnerabilities. 7. Educate IT and security teams about this vulnerability and ensure incident response plans are updated to handle potential exploitation scenarios.
