phpgurukul Nipah Virus Testing Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in version 1.0 of the phpgurukul Nipah virus Testing Management System. The issue resides in the '/new-user-testing.php' file, where the 'govtissuedid' parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited without any login or authorization.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, where attackers can leak, modify, or delete data. Additionally, it could lead to complete control over the system and disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/nipah-tms/new-user-testing.php' with a crafted 'govtissuedid' parameter that includes a SQL injection payload. This payload can be designed to exploit time-based blind SQL injection, such as using a SQL query that causes a delay in the response, indicating successful injection.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input to ensure it meets expected formats, and minimize database user permissions to the least required for operations.
