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-company.php' file, where the 'companyname' parameter is manipulated to inject malicious SQL queries. 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-company.php' with the 'companyname' parameter. The injected SQL payload can be crafted to exploit the application's database query handling, such as by using time-based blind SQL injection techniques.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to separate SQL code from user input. Additionally, input validation and filtering should be applied to ensure that data conforms to expected formats, blocking malicious input. Finally, database user permissions should be minimized, ensuring that the account used for database connections has only the necessary privileges.
