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=delete_borrower', where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized access to the database, modification or deletion of data, and leakage of sensitive information.

Reproduction

To reproduce this vulnerability, send a POST request to '/Loan_Management_System/ajax.php?action=delete_borrower' with a crafted 'id' parameter that includes a SQL injection payload. The injected SQL code can be designed to bypass standard query execution and manipulate the database, such as extracting data or modifying database records.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
