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
home 5G HR02, Wi-Fi STATION SH-52B, and Wi-Fi STATION SH-54C contain an OS command injection vulnerability in the HOST name configuration screen. An arbitrary OS command may be executed with the root privilege by an administrative user.

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 · high confidence

OS command injection vulnerability in the HOST name configuration screen of home 5G HR02, Wi-Fi STATION SH-52B, and Wi-Fi STATION SH-54C allows an authenticated administrative user to execute arbitrary OS commands with root privileges via unsanitized input.

MitigationImplement strict input validation and sanitization on the HOST name configuration parameter to prevent command injection. Avoid using user input in any system() or shell execution calls; if unavoidable, use parameterized approaches or allowlist validation.

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, admin interface, or web UI for the exact model number (HR02, SH-52B, or SH-54C)
    Affected if The device is a home 5G HR02, Wi-Fi STATION SH-52B, or Wi-Fi STATION SH-54C
  2. Check firmware version
    Access the admin web interface, navigate to the system or status page, and record the firmware version displayed
    Affected if The firmware version falls within the affected range for the identified model (compare against vendor's vulnerability disclosure)
  3. Verify admin interface accessibility
    Determine if the administrative web interface is reachable from the network (check for open ports 80/443 or the device's default admin port)
    Affected if The admin interface is exposed on the network without proper access controls
  4. Confirm HOST name configuration access
    Log into the admin interface and navigate to the HOST name configuration screen (typically under network settings, LAN settings, or device configuration)
    Affected if You can access the HOST name configuration screen and the parameter accepts user input without visible sanitization feedback
  5. Inspect HTTP requests for the HOST name parameter
    Use browser developer tools or a proxy to capture the POST request when submitting the HOST name field; examine if the input is sent unsanitized
    Affected if The HOST name value is transmitted as raw input without apparent encoding or validation in the request

You are affected if your device is one of the three listed models, your firmware version is vulnerable, and the administrative HOST name configuration screen is accessible with input acceptance capability.
