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
NETGEAR D6100 devices before 1.0.0.50_0.0.50 are affected by command injection.

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

NETGEAR D6100 devices before firmware version 1.0.0.50_0.0.50 contain an unauthenticated command injection vulnerability. Attackers can execute arbitrary operating system commands by injecting shell metacharacters into vulnerable parameters in the web management interface, leading to full device compromise.

MitigationUpgrade NETGEAR D6100 firmware to version 1.0.0.50_0.0.50 or later. If patching is not possible, disable remote web management and place the device behind a perimeter firewall to limit exposure.

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. Confirm device model is NETGEAR D6100
    Access the device web management interface or check device label/management console to verify the model number is D6100
    Affected if Device model is not NETGEAR D6100 - this check does not apply
  2. Check firmware version
    In the device web management interface, navigate to the Firmware Upgrade or Administration section to view the current firmware version
    Affected if Firmware version is less than 1.0.0.50_0.0.50
  3. Verify web management interface is accessible
    Attempt to access the device web management interface via its IP address (typically http://192.168.1.1)
    Affected if Web management interface is accessible on any network interface (LAN or WAN)

Device is affected if it is a NETGEAR D6100 running firmware version lower than 1.0.0.50_0.0.50 with the web management interface accessible
