Phpgurukul Human Metapneumovirus Testing Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Phpgurukul Human Metapneumovirus (HMPV) Testing Management System version 1.0. The issue resides in the 'searchdata' parameter of the '/patient-report.php' file. This vulnerability allows attackers to inject malicious SQL queries, bypassing input validation and sanitation. Exploitation of this flaw could lead to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, and leakage of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'patient-report.php' with the 'searchdata' parameter. The injection can be crafted to exploit the SQL query handling, such as by closing the original SQL statement and adding a malicious payload. For example, a time-based blind SQL injection can be performed by using a payload that includes a SQL injection technique that delays the response, indicating the injection was successful.

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.
