The Campcodes Online Loan Management System 1.0 is vulnerable to an unauthenticated SQL injection attack that could allow remote adversaries to manipulate database queries.

This vulnerability is an SQL injection flaw (CWE-89) located in the ajax.php file. An unauthenticated attacker can exploit this by injecting malicious SQL commands into the lastname argument to interact with the underlying database.

The exploitation of this vulnerability can lead to unauthorized access to sensitive financial records, potential data exfiltration, or modification of loan data. Given the CVSS score of 7.3, this represents a high-risk security flaw that could compromise the integrity and confidentiality of the application. Business operations relying on this system for loan processing are at significant risk of disruption.

Immediate Action: Since a formal patch is not confirmed, administrators should restrict access to the affected endpoint at the network or web server level and contact the vendor for an urgent security update.

Proactive Monitoring: Monitor database query logs for unusual patterns, such as unexpected SQL syntax or unauthorized access attempts originating from the /ajax.php endpoint.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block SQL injection payloads targeting the lastname parameter.

Public Exploit Available: Yes, a published proof-of-concept exists as documented in the linked GitHub repository.

The presence of a public proof-of-concept elevates the risk of this vulnerability, necessitating immediate attention from security teams. Organizations using Campcodes Online Loan Management System 1.0 must prioritize the implementation of compensating controls, such as WAF rules, to neutralize the threat until a vendor-supplied patch is available. Failure to secure this endpoint could result in unauthorized database access and significant data exposure.
