Description

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.
