PHPGurukul Nipah Virus Testing Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul's Nipah Virus Testing Management System version 1.0. The issue resides in the '/bwdates-report-ds.php' file, where the 'testtype' parameter can be manipulated to inject malicious SQL queries. This vulnerability allows attackers to access and manipulate the database without authorization, potentially leading to unauthorized data access, data modification or deletion, and disruption of services.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, and disruption of services. This poses a significant risk to the system's overall security and operational continuity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/nipah-tms/bwdates-report-ds.php' with the 'testtype' parameter. Inject a payload that includes SQL injection syntax, such as '1' and sleep(3) and', which exploits the application's SQL query handling. This can be done using tools like Burp Suite to intercept and modify the request.

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 that user input conforms to expected formats. Finally, database user permissions should be minimized to limit access rights.
