PHPGurukul Dairy Farm Shop Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Dairy Farm Shop Management System version 1.3. The issue resides in the '/add-product.php' file, where the 'productname' parameter is manipulated to inject malicious SQL code. This vulnerability can be exploited remotely, allowing attackers to access and manipulate the database without authorization.

Impact

Exploitation of this vulnerability could lead to unauthorized database access, allowing attackers to modify or delete data, access sensitive information, and potentially disrupt services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/add-product.php' with a crafted 'productname' parameter that includes malicious SQL payloads. This injected SQL is executed by the application, demonstrating the SQL injection flaw.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, granting only the necessary rights to the account used for database connections.
