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
CG-WLR300NM Firmware version 1.90 and earlier allows an attacker to execute arbitrary OS commands via unspecified vectors.

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

CG-WLR300NM wireless router firmware versions 1.90 and earlier contains an OS command injection vulnerability allowing remote attackers to execute arbitrary operating system commands through unspecified vectors. The vulnerability stems from insufficient input validation in the firmware, enabling attackers to inject malicious commands that are then executed with elevated privileges on the device.

MitigationApply the vendor-supplied firmware update if available; otherwise, replace the end-of-life device with a supported model and implement network segmentation to limit exposure.

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
    Check the device label or web interface for the exact model number - CG-WLR300NM or Corega WLR 300 NM
    Affected if Device is a Corega WLR 300 NM router
  2. Check the firmware version
    Access the router web administration panel and look in the status or system information page for the firmware version, or check the device label for a firmware version sticker
    Affected if Firmware version is 1.90 or lower
  3. Verify remote management access
    Check the router configuration for remote management or WAN access settings - look for 'Remote Management', 'WAN Access', or 'External Access' options in the administration settings
    Affected if The router's web interface or administration ports are accessible from the WAN/internet side
  4. Assess input handling exposure
    Review which router features accept user input - particularly any fields that might process system commands or be passed to shell functions
    Affected if Input fields or parameters on the device are accessible and not properly sanitized before processing

A user is affected if they own a Corega WLR 300 NM router running firmware version 1.90 or earlier, with any management interface accessible to untrusted networks.

Upgrade available Upgrade to a release after 1.90
Interim mitigation

Apply the vendor-supplied firmware update if available; otherwise, replace the end-of-life device with a supported model and implement network segmentation to limit exposure.
