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
An issue was discovered in CommScope Ruckus IoT Controller 1.7.1.0 and earlier. There are Hard-coded System Passwords that provide shell access.

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 Ruckus IoT Controller versions 1.7.1.0 and earlier contain hardcoded system passwords embedded in the firmware or application code. These credentials provide direct shell access to the system, allowing unauthenticated attackers to gain full administrative control over the device.

MitigationLocate and replace all hardcoded credentials with strong, unique passwords or integrate with proper authentication mechanisms. Update to a patched version if available and audit the system for unauthorized access.

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 installed Ruckus IoT Controller version
    Check the product's web interface, command line, or system information for the current software version
    Affected if version displays as 1.7.1.0 or lower
  2. Verify firmware or application version
    If accessible, check the firmware file or application build information for the version number
    Affected if firmware or application version is 1.7.1.0 or earlier
  3. Confirm product is Commscope Ruckus IoT Controller
    Verify the product name and model matches the affected product line
    Affected if device is Commscope Ruckus IoT Controller running version 1.7.1.0 or earlier

If the installed Commscope Ruckus IoT Controller version is 1.7.1.0 or earlier, the hardcoded credentials are present and the environment is affected.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
