Campcodes Online Loan Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Online Loan Management System version 1.0. The issue arises in the file '/ajax.php?action=save_borrower', where the 'lastname' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows unauthorized database access, manipulation of data, and potential leakage of sensitive information. It poses a significant risk to system security and data integrity.

Reproduction

To reproduce this vulnerability, send a POST request to '/Loan_Management_System/ajax.php?action=save_borrower' with the 'lastname' parameter crafted to include a SQL injection payload. The injection can be verified by using a time-based blind SQL injection technique, such as adding a payload that causes the database to delay its response.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
