      "value": "The locally served web site on the Garmin WDU (v1 1.4.6 and v2 5.0) allows a cross-site origin WebSocket hijacking attack. Among other uses, the WDU utilizes WebSockets to control settings, including administrative settings. This allows a network attacker to take full control of a WDU. To initiate an exploit of this vulnerability, the victim must (1) be utilizing a web browser on a multihomed host that has local interfaces on the Garmin Marine Network as well as another network, and (2) access a malicious third party website created by the attacker."

Entre otros usos, el WDU utiliza WebSockets para controlar configuraciones, incluyendo configuraciones administrativas. Esto permite a un atacante de red tomar el control total de un WDU. Para iniciar un exploit de esta vulnerabilidad, la víctima debe (1) estar utilizando un navegador web en un host multihomed que tiene interfaces locales en la red marina de Garmin, así como en otra red, y (2) acceder a un sitio web malicioso de terceros creado por el atacante."
