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
The embedded web interface of the device does not support HTTPS/TLS for authentication and uses HTTP Basic Authentication. Traffic is encoded but not encrypted, exposing user credentials to passive interception by attackers on the same network.

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

The embedded web interface lacks HTTPS/TLS encryption and uses HTTP Basic Authentication, transmitting credentials in base64-encoded format over plaintext HTTP. This allows network attackers to passively intercept and decode user credentials.

MitigationEnable HTTPS/TLS on the web interface and replace HTTP Basic Authentication with more secure authentication mechanisms; if the device cannot support encryption, consider network segmentation or replacing the device with one supporting secure communications.

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. Verify if the web interface is accessible over HTTP
    Attempt to access the device's web interface using http:// (not https://). Check if the connection succeeds and the login page loads over plaintext HTTP.
    Affected if The web interface loads over HTTP without redirecting to HTTPS, indicating HTTPS/TLS is not enforced.
  2. Confirm HTTPS/TLS is not enabled on the web server
    Inspect the web server configuration or device settings to verify whether HTTPS/TLS transport encryption is configured and enabled for the web interface.
    Affected if HTTPS/TLS is disabled or not configured for the web interface.
  3. Identify the authentication mechanism in use
    Examine the HTTP response headers or the login page source when accessing the HTTP endpoint. Look for signs of HTTP Basic Authentication (e.g., WWW-Authenticate header, no session-based login form).
    Affected if HTTP Basic Authentication is being used, indicated by a browser login prompt or WWW-Authenticate header appearing over HTTP.
  4. Verify credentials are transmitted over plaintext HTTP
    Use a network capture tool (e.g., Wireshark, tcpdump) to observe traffic when authenticating to the web interface over HTTP. Confirm that base64-encoded credentials are sent in the HTTP Authorization header.
    Affected if Credentials are transmitted in base64 format within unencrypted HTTP traffic.

You are affected if the web interface is accessible over plaintext HTTP and uses HTTP Basic Authentication, allowing credentials to be intercepted in base64-encoded form.

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.
