Code-Projects Vehicle Management SQL Injection Vulnerability in filter1.php

A critical SQL injection vulnerability has been identified in the Code-Projects Vehicle Management application, version 1.0. The issue resides in the filter1.php file, where the vehicle 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, with potential consequences including unauthorized database access, data manipulation, and access to sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to filter1.php with a crafted vehicle parameter that includes SQL injection payloads. Various types of SQL injection techniques can be used, such as boolean-based blind, error-based, time-based blind, and UNION-based injections. The injected SQL payloads can be used to extract database information, manipulate database contents, or potentially execute commands on the server, depending on the application's database handling and configuration.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to separate SQL code from user input, validate and filter user input to ensure it meets expected formats, minimize database user permissions, and conduct regular security audits.
