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 web server of the device performs exchanges of sensitive information in clear text through an insecure protocol.

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 web server on the affected device transmits sensitive information (such as authentication credentials, session data, or personal information) in clear text over an insecure protocol, likely HTTP instead of HTTPS or unencrypted network communication. This allows attackers on the network path to intercept and read sensitive data in transit.

MitigationEnable and enforce TLS/HTTPS for all web server communications, ensuring sensitive data is encrypted in transit. Verify that the device supports encrypted protocols and configure it to use secure communication channels exclusively.

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 HTTP port accessibility
    Check if the device's web server is listening on port 80 (HTTP) using commands like 'netstat -an | grep :80' or 'nmap -p 80 <device_ip>'
    Affected if Port 80/HTTP is open and accessible on the device
  2. Confirm HTTPS is not enabled or enforced
    Check if port 443 (HTTPS) is open using 'netstat -an | grep :443' or attempt to access the device via https:// URL
    Affected if HTTPS is not listening or redirects/falls back to HTTP
  3. Inspect web traffic for cleartext transmission
    Use a packet capture tool (like Wireshark or tcpdump) while authenticating or accessing sensitive pages. Filter for HTTP traffic on port 80
    Affected if Authentication credentials, session cookies, or personal data are visible in clear text over HTTP
  4. Review web server configuration files
    Examine the device's web server configuration for SSL/TLS settings. Look for directives enabling 'ssl', 'tls', or 'https'
    Affected if SSL/TLS is disabled or no secure protocol is configured
  5. Check for secure transport enforcement
    Attempt to access the web interface over HTTP and observe whether the server redirects to HTTPS or rejects the connection
    Affected if HTTP access is accepted without redirect to HTTPS and sensitive data can be transmitted

The device is affected if its web server accepts unencrypted HTTP connections and transmits authentication credentials, session data, or personal information in clear text without enforcing HTTPS/TLS.
