Code-Projects Courier Management System SQL Injection Vulnerability in add-courier.php

A SQL injection vulnerability has been identified in Code-Projects Courier Management System version 1.0. The issue arises in the add-courier.php file, where the Shippername parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to the add-courier.php file with the Shippername parameter manipulated to include a crafted SQL payload. The injection can be verified by observing the application's response, which may indicate successful exploitation, such as returning database information or application data that should not be accessible.

Remediation

It is recommended to implement input validation and sanitization for the Shippername parameter to prevent SQL injection. Additionally, using prepared statements for database queries can help mitigate this vulnerability.
