CVE-2025-27852

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.

5.0 3.1 MEDIUM

Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
