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
This vulnerability applies to the Micro Air Vehicle Link (MAVLink) protocol and allows a remote attacker to gain access to sensitive information provided it has access to the communication medium. MAVLink is a header-based protocol that does not perform encryption to improve transfer (and reception speed) and efficiency by design. The increasing popularity of the protocol (used accross different autopilots) has led to its use in wired and wireless mediums through insecure communication channels exposing sensitive information to a remote attacker with ability to intercept network traffic.

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

MAVLink protocol lacks encryption by design to maximize transfer speed and efficiency. A remote attacker with access to the communication medium (wired or wireless) can intercept unencrypted MAVLink traffic and gain access to sensitive information such as telemetry data, command signals, and system configuration details.

MitigationImplement encryption wrapper around MAVLink communications or use secure communication channels (e.g., VPN, TLS tunnel) to protect data in transit; alternatively, restrict communication to isolated/air-gapped networks.

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 MAVLink protocol in use
    Inspect network traffic captures, system logs, or running processes for MAVLink packet signatures (MAVLink frames typically begin with STX byte 0xFE followed by payload length, sequence number, system ID, component ID, and message ID)
    Affected if MAVLink protocol traffic is detected in the environment
  2. Verify encryption wrapper is configured
    Examine the MAVLink communication configuration files or implementation to determine if an external encryption layer (such as a VPN, TLS tunnel, or MAVLink encryption module) is actively wrapping the MAVLink stream
    Affected if No encryption wrapper, VPN, TLS tunnel, or secure channel is configured around MAVLink communications
  3. Check network isolation status
    Review network architecture and firewall rules to verify whether the MAVLink communication path is physically or logically isolated from untrusted networks, or connected to shared/wireless mediums accessible to attackers
    Affected if MAVLink traffic traverses non-isolated networks or the communication medium is accessible to unauthorized remote attackers

Your environment is affected if MAVLink protocol is in use without an encryption wrapper, secure tunnel, or complete network isolation from untrusted communication paths.

Mitigation

Implement encryption wrapper around MAVLink communications or use secure communication channels (e.g., VPN, TLS tunnel) to protect data in transit; alternatively, restrict communication to isolated/air-gapped networks.
