How the Exploit Works
The exploit works by taking advantage of a CSRF vulnerability in the Appointment Booking Calendar. An attacker tricks the victim into clicking a link or loading a page that contains a malicious request. This request is then sent from the victim’s browser, with all their authentication details, to the website or application that the attacker is targeting. Since the website or application believes the request to be legitimate, it processes the request. In this case, the malicious request contains an SQL injection, which manipulates the database query process and allows the attacker to view, modify or delete data from the database.
Conceptual Example Code
Here’s a simplified conceptual example of a malicious HTTP request exploiting this vulnerability:
POST /appointment/book HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
csrf_token=...&appointment_id=1; DROP TABLE users; --In the above example, the attacker crafted a `POST` request to book an appointment. The `appointment_id` parameter is manipulated with SQL commands `DROP TABLE users; –` that could potentially delete the user’s database if the server processes this request.
The safety and security of any platform or application are of utmost importance. As such, it is highly recommended for users and providers of the Appointment Booking Calendar to apply the vendor patch as soon as possible. In the meantime, using a Web Application Firewall or Intrusion Detection System could serve as a temporary mitigation measure.
