PHPGurukul COVID19 Testing Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul's COVID19 Testing Management System version 1.0. The issue arises in the file '/patient-report.php', where the 'searchdata' parameter is processed without proper validation, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions could disrupt services and pose a significant threat to overall system security and business operations.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/patient-report.php' with the 'searchdata' parameter. The injected SQL payload can be crafted to exploit the SQL injection vulnerability, such as by using time-based blind injection techniques or union-based injection to extract database information.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
