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
On Televes COAXDATA GATEWAY 1Gbps devices doc-wifi-hgw_v1.02.0014 4.20, the backup/restore feature lacks access control, related to ReadFile.cgi and LoadCfgFile.

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 Televes COAXDATA GATEWAY 1Gbps devices running firmware doc-wifi-hgw_v1.02.0014 4.20 have an authentication bypass vulnerability in the backup/restore functionality. The ReadFile.cgi and LoadCfgFile CGI scripts can be accessed without any authentication, allowing unauthenticated attackers to read sensitive configuration files or upload malicious configuration updates.

MitigationApply vendor firmware update when available; until then, isolate affected devices behind a firewall with strict access controls, or replace end-of-life devices with supported alternatives.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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
    Log into the device web interface or check the device label to confirm it is a Televes COAXDATA GATEWAY 1Gbps device
    Affected if The device is NOT a Televes COAXDATA GATEWAY 1Gbps model
  2. Check the firmware version
    Access the device administration panel and navigate to the firmware or status page to view the installed firmware version. Compare it to version 1.02.0014_4.20
    Affected if The firmware version is exactly 1.02.0014_4.20
  3. Verify CGI script accessibility
    Attempt to access the URLs /cgi-bin/ReadFile.cgi and /cgi-bin/LoadCfgFile.cgi from a browser or curl command without providing any authentication credentials
    Affected if The CGI scripts respond without requiring a login (HTTP 200 OK instead of redirecting to login or returning 401/403)

You are affected if you have a Televes COAXDATA GATEWAY 1Gbps running firmware version 1.02.0014_4.20 and the ReadFile.cgi or LoadCfgFile.cgi scripts are accessible without authentication.
