Executive brief
sfturing hosp_order is a hospital appointment scheduling system. An unauthenticated attacker can cancel any patient's appointment by manipulating an order ID parameter, bypassing all authorization checks. This allows unauthorized disruption of medical service scheduling and can trigger cancellation penalties on other patients' accounts.
Technical details
The vulnerability is an authorization bypass (CWE-639: Unverified Ownership) in the OrderController.cancelOrder endpoint (POST /cancelOrder/{id}). The vulnerable component executes the order cancellation immediately via orderRecordsService.cancelOrder(id) before checking if a user exists in the session. No authentication verification or ownership relationship validation occurs—the endpoint processes any numeric ID without verifying the requester's identity or authorization. The attack vector is network-based with no authentication required, no user interaction needed, and no access control preconditions. An attacker can craft a simple HTTP POST request with an arbitrary order ID to cancel any appointment. The project uses a rolling release model and has not yet responded to the early disclosure.
