CVE-2025-9505 is a security vulnerability identified in version 1.0 of the Campcodes Online Loan Management System. The flaw exists in the /ajax.php endpoint, specifically when handling requests with the action parameter set to save_loan_type. The vulnerability arises from improper sanitization or validation of the 'ID' argument, which allows an attacker to perform SQL injection attacks. This means that an attacker can inject malicious SQL code into the backend database query, potentially manipulating or extracting sensitive data, modifying database contents, or causing denial of service by disrupting database operations. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing the risk of automated or widespread exploitation. 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, and limited impact on confidentiality, integrity, and availability. Although no public exploits are currently known in the wild, the existence of a published exploit increases the likelihood of future attacks. The affected system is a loan management platform, which typically handles sensitive financial and personal data, making the impact of a successful attack potentially significant.

For European organizations using Campcodes Online Loan Management System 1.0, this vulnerability poses a risk of unauthorized data access or manipulation. Financial institutions or loan service providers could face data breaches exposing customer personal and financial information, leading to regulatory non-compliance under GDPR and potential financial penalties. Integrity of loan data could be compromised, affecting business operations and customer trust. Availability impact, while limited, could disrupt loan processing services, causing operational delays. The remote and unauthenticated nature of the exploit increases the risk of automated attacks targeting vulnerable installations. Given the sensitivity of financial data and strict European data protection laws, exploitation could have severe reputational and legal consequences for affected organizations.

Organizations should immediately assess their use of Campcodes Online Loan Management System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement web application firewall (WAF) rules specifically targeting SQL injection patterns on the /ajax.php?action=save_loan_type endpoint, focusing on sanitizing or blocking suspicious 'ID' parameter inputs. Conduct thorough input validation and parameterized query enforcement in custom deployments or code forks. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. Restrict network access to the management system to trusted IP ranges where feasible. Additionally, perform regular security audits and penetration testing to detect similar injection flaws. Finally, prepare incident response plans to quickly contain and remediate any exploitation attempts.
