Empirbus Wireless Display Unit Firmware

The locally served web site on the Garmin WDU (v1 1.4.6 and v2 5.0) allows its authentication to be bypassed. The WDU web site only performs authentication with the client within the client's browser. The WebSockets used to communicate with the WDU server do not enforce any authentication. An attacker may bypass all authentication mechanisms by directly utilizing the remote APIs available on the websocket.Show less

The locally served web site on the Garmin WDU (v1 1.4.6 and v2 5.0) allows a reflected cross site scripting (XSS) attack. This allows an attacker on the local network segment to execute arbitrary JavaScript code within the context of the WDU webpage. Full administrator level access to the device is possible. To initiate an exploit of this vulnerability, the victim must execute two actions: (1) view a specific URL served by the WDU, and (2) click an element on the rendered page.Show less

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.Show less

The locally served web site on the Garmin WDU (v1 1.4.6 and v2 5.0) allows a symlink attack. If a malicious graphics package containing symlinks is uploaded, the web server follows the supplied links when serving content. No mechanisms to restrict those link targets to a specific area of the filesystem is enabled. This allows an attacker to retrieve arbitrary files from the device.Show less
