PHPGurukul Beauty Parlour Management System SQL Injection Vulnerability in View Enquiry File

A SQL injection vulnerability has been identified in PHPGurukul Beauty Parlour Management System version 1.1. The issue resides in the '/admin/view-enquiry.php' file, where the 'viewid' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation or deletion of data, and leakage of sensitive information. Such actions could disrupt services and compromise overall system security.

Reproduction

The vulnerability can be reproduced by sending a GET request to the '/admin/view-enquiry.php' file with a crafted 'viewid' parameter. This can be done using a web browser or a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities. The injected SQL payloads can be time-based blind injection techniques, such as using 'SLEEP' functions, or UNION-based injections to extract data from the database.

Remediation

It is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input meets expected formats, thereby blocking malicious data. Minimizing database user permissions is also advised, ensuring that the database account used has only the necessary rights and avoiding high-privilege accounts for regular operations.
