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 EDS-4000/G4000 Series prior to version 3.2 includes IP forwarding capabilities that users cannot deactivate. An attacker may be able to send requests to the product and have it forwarded to the target. An attacker can bypass access controls or hide the source of malicious requests.

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 EDS-4000/G4000 Series network devices contain a non-disableable IP forwarding feature prior to firmware version 3.2. This allows an attacker to route traffic through the compromised device, effectively using it as a proxy to bypass network access controls and mask the origin of malicious requests.

MitigationUpdate firmware to version 3.2 or later, which reportedly adds the ability to deactivate IP forwarding. If immediate patching is not feasible, implement network segmentation and firewall rules to restrict the device from forwarding unauthorized traffic.

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. Confirm device model is in the affected series
    Access the device web interface, CLI, or use SNMP to identify the exact model number. Verify it is one of: EDS-4008, EDS-4009, EDS-4012, EDS-4014, EDS-G4008, EDS-G4012, or EDS-G4014.
    Affected if The device model matches one of the listed affected models.
  2. Check installed firmware version
    Access the device web interface (System > Firmware or About page), CLI (show version or show system-info), or SNMP to retrieve the current firmware version.
    Affected if The firmware version is 3.2 or lower.
  3. Verify IP forwarding is enabled
    Access the device web interface under Network > IP Forwarding or Routing > IP Forwarding settings. Check the current status of the IP forwarding feature.
    Affected if IP forwarding is currently enabled on the device.

The device is affected if it is an EDS-4000 or G4000 series model running firmware version 3.2 or lower with IP forwarding enabled.

Upgrade available Upgrade to a release after 3.2
Interim mitigation

Update firmware to version 3.2 or later, which reportedly adds the ability to deactivate IP forwarding. If immediate patching is not feasible, implement network segmentation and firewall rules to restrict the device from forwarding unauthorized traffic.

Recommended fix Moderate confidence

Firmware version 3.2 or later

  1. 1. Identify the exact model number of your EDS-4000/G4000 series device (e.g., EDS-4008, EDS-G4012)
  2. 2. Access the device's web interface or console
  3. 3. Navigate to the firmware upgrade section
  4. 4. Download the latest firmware version from Moxa's official support website (www.moxa.com)
  5. 5. Upload and apply firmware version 3.2 or later
  6. 6. After upgrade, verify that IP forwarding can now be deactivated in the device settings
  7. 7. If IP forwarding is not needed, disable it to mitigate the vulnerability
  8. 8. Verify the device is functioning correctly after the upgrade
