Code-Projects Inventory Management System SQL Injection Vulnerability in removeBrand.php

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Inventory Management System. The issue resides in the file /php_action/removeBrand.php, where the 'brandId' 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 data access, data modification or deletion, and in some cases, executing administrative operations on the database. The vulnerability poses a significant risk to the application's data integrity and security.

Reproduction

To reproduce this vulnerability, send a POST request to /php_action/removeBrand.php with the 'brandId' parameter. The request can include a payload that exploits the SQL injection vulnerability, such as a boolean-based blind injection or a time-based blind injection that uses the SQL SLEEP function.

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.
