A critical SQL injection vulnerability in Campcodes Online Loan Management System 1.0 allows for remote unauthorized database interaction.

The application is susceptible to SQL injection via the ID parameter in the /ajax.php?action=delete_loan endpoint. The vulnerability is exploitable by unauthenticated remote attackers.

The ability to perform SQL injection allows an attacker to execute arbitrary queries against the application database. This can lead to unauthorized data disclosure, modification of loan records, or complete compromise of the backend database. With a CVSS score of 7.3, this represents a high-severity risk that could result in significant operational disruption and loss of data integrity.

Immediate Action: As no official patch is currently available, administrators should restrict access to the /ajax.php endpoint or disable the affected functionality until a vendor update is released.

Proactive Monitoring: Review web server access logs for anomalous requests containing SQL syntax or unusual parameters directed toward the /ajax.php file.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block SQL injection patterns to mitigate the risk of exploitation.

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

Given the availability of a public proof-of-concept and the ease of remote exploitation, this vulnerability poses a significant risk to affected environments. Organizations using Campcodes Online Loan Management System 1.0 must prioritize restricting network access to the vulnerable endpoint and monitor for signs of unauthorized database manipulation until an official security patch is provided by the vendor.
