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
Unspecified vulnerability in the SSH implementation on D-Link Japan DES-3800 devices with firmware before R4.50B58 allows remote authenticated users to cause a denial of service (device hang) via unknown vectors, a different vulnerability than CVE-2013-5998.

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

Vulnerability in the SSH service on D-Link DES-3800 switches running firmware versions prior to R4.50B58 allows any remote authenticated user to crash the device, causing a denial of service. The specific technical mechanism is not disclosed.

MitigationUpdate D-Link DES-3800 firmware to version R4.50B58 or later to remediate this vulnerability.

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 device model
    Access the switch CLI or web interface and run 'show switch' or check the device hostname/model information to confirm it is a D-Link DES-3800 switch
    Affected if Device model is D-Link DES-3800 and is running vulnerable firmware
  2. Check the firmware version
    Run 'show firmware version' or check the firmware revision in the web interface under the System > Firmware Upgrade or Status section
    Affected if Firmware version is prior to R4.50B58 (versions 4.00, 4.50, or any version below R4.50B58)
  3. Verify SSH service is enabled
    Run 'show ip ssh' or 'show ssh' in the CLI to check if the SSH service is enabled on the switch
    Affected if SSH service is enabled and running on the device
  4. Check for authenticated SSH sessions
    Run 'show ssh session' or 'show users' to see if any authenticated SSH sessions are currently active
    Affected if Any authenticated SSH user session exists on the device

A D-Link DES-3800 switch is affected if it runs firmware prior to R4.50B58 and has SSH service enabled with at least one authenticated user session present.
