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 resides in the file '/patient/appointment.php' within the 'scheduleDate' parameter. This vulnerability allows remote attackers to inject malicious SQL queries, exploiting insufficient input validation. The consequences of this vulnerability include unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, leading to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Such actions could disrupt services and cause significant harm to system integrity and business operations.

Reproduction

The vulnerability can be reproduced by sending a crafted GET request to '/patient/appointment.php' with a malicious payload in the 'scheduleDate' parameter. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall system security.
