Projectworlds Online Doctor Appointment Booking System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the Online Doctor Appointment Booking System, version 1.0. The issue arises in the file '/patient/profile.php?patientId=1', where the 'patientFirstName' parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially affecting other parameters as well.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, leading to data manipulation, unauthorized data access, and potential disruption of service.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/patient/profile.php?patientId=1' with a crafted 'patientFirstName' parameter that includes malicious SQL payloads. The injection can be verified by using SQL injection testing tools, such as sqlmap, 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.
