PHPGurukul Company Visitor Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Company Visitor Management System version 2.0. The issue resides in the '/admin-profile.php' file, where the 'adminname' and 'mobilenumber' parameters can be manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, allowing attackers to access and manipulate the database, 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 or deletion of data, leakage of sensitive information, and could result in complete control over the system, causing service disruptions.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/cvms/admin-profile.php' with the 'mobilenumber' parameter crafted to include a SQL injection payload. This payload can be designed to exploit time-based blind SQL injection, such as using the 'SLEEP' function to create a delay, indicating successful injection.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, and minimize database user permissions.
