CVE-2016-6544
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 · uneditedgetgps data in iTrack Easy can be modified without authentication by setting the data using the parametercmd:setothergps. This vulnerability can be exploited to alter the GPS data of a lost 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 tracking system allows unauthenticated modification of device GPS coordinates via the cmd:setothergps parameter. An attacker can send requests to set arbitrary GPS data without any authentication, enabling location spoofing for lost or stolen devices.

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 Itrack Easy deploymentInventory your GPS tracking systems and confirm if any Ieasytec Itrack Easy devices or associated software are present in your environment.Affected if Itrack Easy system is deployed in the network or as part of your asset inventory.
-
Locate the GPS command endpointIdentify networkaccessible interfaces for the Itrack Easy system such as mobile apps, web portals, or API endpoints that communicate with the device. Look for endpoints that accept GPS-related commands.Affected if The system exposes an HTTP/HTTPS interface accepting the cmd:setothergps parameter.
-
Test unauthenticated GPS coordinate modificationSend a crafted request to the Itrack Easy interface with the cmd:setothergps parameter containing arbitrary GPS coordinates without including any authentication tokens, session cookies, or credentials.Affected if The request successfully modifies GPS coordinates and the system returns a success response without rejecting the unauthenticated request.
-
Verify authentication requirementReview the API documentation or intercept network traffic to confirm whether the GPS modification endpoint requires authentication, authorization headers, or valid session tokens.Affected if No authentication or authorization mechanism is enforced for the cmd:setothergps command.
You are affected if you have deployed Itrack Easy and the GPS coordinate modification endpoint is accessible without requiring authentication credentials.

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 authentication and proper authorization checks for all GPS data modification endpoints, ensuring only verified device owners can update location information.
