CVE-2016-6543
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 · uneditedA captured MAC/device ID of an iTrack Easy can be registered under multiple user accounts allowing access to getgps GPS data, which can allow unauthenticated parties to track the device.
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 · moderate confidenceThe iTrack Easy GPS device's MAC/device ID can be registered under multiple user accounts in the getgps service, allowing anyone who captures a device ID to register it and access the device's real-time location data without proper authorization.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify if the Itrack Easy GPS service is exposedDetermine if the getgps service endpoint is accessible on the device or through a cloud portal by checking network configurations and published service URLsAffected if The getgps service is externally accessible without network restrictions
-
Test device ID registration behaviorAttempt to register the same MAC/device ID under two different user accounts using the getgps service registration interfaceAffected if The service allows the same device ID to be associated with multiple user accounts
-
Verify authentication requirements for GPS data accessAttempt to access location data through the getgps service without providing valid credentials or session tokensAffected if GPS location data can be retrieved without authentication
-
Confirm device ID capture exposureReview logs or network traffic to determine if device MAC/ID values are transmitted in plain text or can be intercepted easilyAffected if Device IDs are transmitted without encryption or can be captured by unauthenticated parties
-
Check for account linkage validationReview the getgps service configuration or API responses to see if the system validates that the requesting user owns the device before returning location dataAffected if The service returns location data to any user who provides a valid device ID, regardless of account ownership
A user is affected if the getgps service is accessible and allows device IDs to be registered under multiple accounts or returns location data without verifying account ownership.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement server-side validation to ensure each device ID/MAC address can only be associated with a single user account, and add authentication requirements for accessing GPS data.
