This dishwasher is not an appliance, but a professional tool. This is a washer-disinfector for hospitals and labs, with options like barcode scanners and printers, and more. Connecting a professional dishwasher like this is far from useless, at least for remote maintenance and everything. Once again, this is Industrial IoT, not home automation.
Then, this makes the vulnerability even worse. Do we want to take risks with a disinfector that washes hospital equipment? No, and having a bug that brings us back to the 1990's and the early days of the Web shows how device vendors are playing catchup without realizing the investment required.
