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
Huawei Honor WS851 routers with software 1.1.21.1 and earlier allow remote attackers to obtain sensitive information via unspecified vectors, aka HWPSIRT-2016-05053.

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 Huawei Honor WS851 router with firmware 1.1.21.1 and earlier contains an information disclosure vulnerability allowing remote attackers to obtain sensitive information through unspecified vectors. The CVSS 7.5 score indicates high exploitability with network-level access, suggesting the flaw likely involves improper access controls or exposed management interfaces leaking credentials, configuration data, or session information.

MitigationApply any available firmware update from Huawei for the WS851 router. If no patch exists, consider network segmentation to isolate the device, disable remote management interfaces, or replace the device with a supported model.

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 router admin interface or check the device label to confirm the exact model is Huawei Honor WS851
    Affected if The device is not a Huawei Honor WS851 router, then it is not affected by this specific CVE
  2. Determine the firmware version
    Log into the router web interface (typically at 192.168.1.1) and navigate to System Settings or Status to find the firmware version. Alternatively, check the Huawei support site or the device label for firmware version information.
    Affected if The installed firmware version is 1.1.21.1 or earlier, indicating the device is vulnerable
  3. Check if remote management interface is exposed
    Attempt to access the router web interface from an external network (WAN side) or review port forwarding/firewall rules to determine if ports 80, 443, or the management interface are accessible from the internet
    Affected if Remote management or the admin web interface is accessible from the WAN, increasing exposure to this information disclosure flaw
  4. Review network exposure
    Use external port scanning tools (such as Nmap) from outside your network to check if common management ports (HTTP/HTTPS) are open and reachable on the router's public IP address
    Affected if Management ports are open to the internet, indicating the device may be exploitable via network-level attack vectors

A user is affected if they have a Huawei Honor WS851 router running firmware version 1.1.21.1 or earlier with its management interface potentially exposed to network-level access.
