Mobile Devices (aka MDI) C4 OBD-II dongles with firmware 2.x and 3.4.x, as used in Metromile Pulse and other products, do not validate firmware updates, which allows remote attackers to execute arbitrary code by specifying an update server.
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
