itsourcecode Online Loan Management System SQL Injection Vulnerability in load_fields.php

A SQL injection vulnerability has been identified in the Online Loan Management System version 1.0, specifically in the load_fields.php file. This issue arises from inadequate validation of the loan_id parameter, allowing attackers to inject malicious SQL queries. The vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could lead to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to load_fields.php with the loan_id parameter. The request can include a payload that exploits the SQL injection vulnerability, such as a time-based blind SQL injection payload that uses the SQL SLEEP function to delay the 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.
