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.

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

A stack-based buffer overflow vulnerability in NEC Aterm routers allows unauthenticated remote attackers to execute arbitrary commands via specially crafted network requests. The overflow occurs in the stack memory region, likely due to insufficient bounds checking on user input before copying to a fixed-size stack buffer.

MitigationApply vendor firmware updates immediately; if no patch exists, consider network segmentation or device replacement. Disable remote management interfaces exposed to the internet as an interim control.

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

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 router model
    Locate the device label on the router or log into the admin web interface (typically at 192.168.0.1 or 192.168.1.1) and check the model name displayed in the status or system information page
    Affected if The model matches any of the following: Wg1800hp4, Wg1200hs3, Wg1900hp2, Wg1200hp3, Wg1800hp3, Wg1200hs2, Wg1900hp, Wg1200hp2
  2. Confirm firmware version
    In the router admin interface, navigate to the firmware or system information section and note the installed firmware version number
    Affected if All versions of the listed models are affected; if your model is on the list, you are vulnerable regardless of version
  3. Check remote management exposure
    In the router admin interface, locate the remote management or WAN access settings (often under Advanced, Security, or Access Control settings) and verify if remote administration from the internet is enabled
    Affected if Remote management interfaces accessible from the internet provide the attack vector for unauthenticated network requests to trigger the overflow

You are affected if you are using any of the listed NEC Aterm models with remote management exposed to the internet, since all firmware versions contain the vulnerability.
