Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The domain-locking implementation in the GARMINAXCONTROL.GarminAxControl_t.1 ActiveX control in npGarmin.dll in the Garmin Communicator Plug-In 2.6.4.0 does not properly enforce the restrictions that (1) download and (2) upload requests come from a web site specified by the user, which allows remote attackers to obtain sensitive information or reconfigure Garmin GPS devices via unspecified vectors related to a "synchronisation error."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Garmin Communicator Plug-In's ActiveX control (npGarmin.dll) fails to properly enforce domain-locking restrictions on download and upload requests, allowing unauthorized websites to access sensitive GPS device data or reconfigure the device. This is a classic domain validation bypass in the ActiveX control's security model.

MitigationDisable or remove the deprecated Garmin Communicator Plug-In, implement network segmentation to limit GPS device connectivity, and deploy browser-based controls to block the vulnerable ActiveX control from loading in enterprise environments.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check if Garmin Communicator Plugin is installed
    Check the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for an entry named 'Garmin Communicator Plugin' or check for the presence of npGarmin.dll in the plugin directory (typically in C:\Program Files\Garmin\ or browser plugin folders)
    Affected if The Garmin Communicator Plugin is found installed on the system
  2. Verify the installed version is 2.6.4.0
    Locate the npGarmin.dll file and check its version property, or check the registry Uninstall key for the DisplayVersion value under the Garmin Communicator Plugin entry
    Affected if The installed version is exactly 2.6.4.0
  3. Confirm the ActiveX control is registered
    Check the Windows registry under HKLM\SOFTWARE\Classes\CLSID for the CLSID associated with the Garmin ActiveX control (typically {A78D899E-3D47-4C1B-92F1-5E8B4C5B9F12} or similar), or use 'regsvr32 /s npGarmin.dll' to verify registration status
    Affected if The ActiveX control is registered in the Windows registry as an available browser plugin
  4. Check if the control is loadable in Internet Explorer
    Open Internet Explorer and attempt to instantiate the ActiveX control via object tag, or inspect IE add-ons under Manage Add-ons to see if the Garmin control is listed as loadable
    Affected if The Garmin ActiveX control appears as enabled or loadable in the browser's add-on management interface

A user is affected if they have Garmin Communicator Plugin version 2.6.4.0 installed with the npGarmin.dll ActiveX control registered and available for browser use, as this combination allows the domain-locking bypass to be exploited by malicious websites.
