CVE-2023-41926
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 · uneditedThe webserver utilizes basic authentication for its user login to the configuration interface. As encryption is disabled on port 80, it enables potential eavesdropping on user traffic, making it possible to intercept their credentials.
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 confidenceThe webserver uses basic authentication (which transmits credentials in base64 encoding) over unencrypted HTTP on port 80. This allows attackers on the same network or in a man-in-the-middle position to intercept and decode user credentials, enabling unauthorized access to the configuration interface.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify HTTP port 80 is listening and accessibleScan the target server using 'nmap -p 80 <target>' or check if port 80 is open with 'netstat -an | grep :80' or 'ss -tlnp | grep :80'Affected if Port 80 is open and accepting connections, meaning unencrypted HTTP traffic can be received
-
Confirm basic authentication is required over HTTPSend an HTTP request to port 80 (e.g., using curl -v http://<target>/) and check if the response contains a 401 status with 'WWW-Authenticate: Basic' headerAffected if The server returns a 401 Unauthorized response with Basic authentication challenge on port 80
-
Check if HTTPS port 443 is enabled and accessibleScan for port 443 with 'nmap -p 443 <target>' and attempt a request with 'curl -k -v https://<target>/' to see if HTTPS is configuredAffected if Port 443 is closed or HTTPS is not responding, indicating encryption is not available
-
Verify TLS/SSL configuration on HTTPS endpointIf port 443 is open, test TLS configuration using 'openssl s_client -connect <target>:443' or SSLyze/SSLscan tools to check certificate and protocol settingsAffected if TLS is not configured, self-signed certificate is in use without proper trust, or HTTPS is not enforcing encrypted authentication
The environment is affected if HTTP port 80 is open and basic authentication is challengeable over that unencrypted connection while HTTPS (port 443) is either unavailable or not properly configured for secure authentication.

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.
From vendor dataEnable TLS/SSL encryption on the webserver (configure HTTPS on port 443), obtain and properly configure a valid SSL certificate, and ensure all authentication occurs over the encrypted connection rather than the unencrypted port 80.
