Projectworlds Online Doctor Appointment Booking System SQL Injection Vulnerability in Deleteschedule.php

A critical SQL injection vulnerability has been identified in the Online Doctor Appointment Booking System version 1.0, specifically within the file '/doctor/deleteschedule.php'. This vulnerability arises from inadequate validation of user input in the 'id' parameter, allowing attackers to inject malicious SQL queries. Exploitation of this vulnerability could lead to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Notably, this vulnerability can be exploited remotely without any authentication requirements.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized database access, leakage of sensitive data, unauthorized data modification or deletion, and potential disruption of service.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/doctor/deleteschedule.php' with a crafted 'id' parameter that includes malicious SQL payloads. 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 implement prepared statements and parameter binding to separate SQL code from user input, validate and filter input data, minimize database user permissions, and conduct regular security audits.
