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
WS5800-10 version 10.0.3.25 has a denial of service vulnerability. Due to improper verification of specific message, an attacker may exploit this vulnerability to cause specific function to become abnormal.

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

WS5800-10 version 10.0.3.25 contains a denial of service vulnerability stemming from improper verification of specific messages, allowing an attacker to cause a specific function to become abnormal.

MitigationApply any vendor-supplied firmware patches or updates that address this vulnerability; if no patch is available, implement network segmentation and access controls to limit exposure to untrusted network paths.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 device management interface or check the physical device label to confirm the model is Huawei WS5800-10
    Affected if The device is not a Huawei WS5800-10 model
  2. Check the firmware version
    Log into the device management interface and navigate to the system information or firmware version section, or use the command line interface to run 'display version' or similar firmware version command
    Affected if The installed firmware version is 10.0.3.25
  3. Verify the specific version match
    Confirm that the firmware version is exactly 10.0.3.25 (not a different version number in the 10.0.x range)
    Affected if The firmware version is exactly 10.0.3.25
  4. Confirm network exposure
    Determine if the device management interface is accessible from untrusted network segments
    Affected if The device management interface is exposed to untrusted networks

You are affected only if you have a Huawei WS5800-10 device running exactly firmware version 10.0.3.25 and the device is accessible to network attackers.
