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
Insecure permissions in the setNFZEnable function of Autel Robotics EVO Nano drone v1.6.5 allows attackers to breach the geo-fence and fly into no-fly zones.

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 confidence

The setNFZEnable function in Autel Robotics EVO Nano drone firmware v1.6.5 lacks proper permission controls, allowing unauthenticated or unauthorized attackers to disable geo-fence restrictions and operate the drone in regulated no-fly zones.

MitigationApply vendor firmware patch when available; until then, implement compensating controls such as restricting drone operation to approved airspace and monitoring for unauthorized firmware modifications.

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. Identify the firmware version installed on the Autel EVO Nano drone
    Access the drone's settings or companion application and locate the firmware version information. On Autel drones, this is typically found in the Settings > About section of the Autel Sky app or through the drone's maintenance interface.
    Affected if The installed firmware version is exactly 1.6.5, matching the affected version listed in the CVE.
  2. Verify the presence of the setNFZEnable function
    Examine the firmware binary or API interface for the setNFZEnable function. This may require access to the drone's debug or maintenance interface, or reviewing firmware analysis reports if available.
    Affected if The setNFZEnable function is present in the firmware build, indicating the vulnerable code path exists.
  3. Confirm the drone's geo-fence or No-Fly Zone (NFZ) status
    Check the drone's current geo-fence configuration through the Autel Sky app or flight controller settings. Look for any indication that NFZ enforcement is disabled or bypassed.
    Affected if The geo-fence restriction is found to be disabled or non-functional when it should be active.
  4. Inspect network or communication logs for unauthorized setNFZEnable calls
    If logging or network capture is available, review logs for any setNFZEnable function calls that may have been invoked, especially from unauthenticated or unexpected sources.
    Affected if There are logs or evidence of setNFZEnable being called without proper authentication or authorization.

The environment is affected if the Autel EVO Nano drone is running firmware version 1.6.5 and the setNFZEnable function is accessible, allowing geo-fence restrictions to be disabled.
