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
A CWE-1021: Improper Restriction of Rendered UI Layers or Frames vulnerability exists that could cause an adversary to trick the interface user/admin into interacting with the application in an unintended way when the product does not implement restrictions on the ability to render within frames on external addresses. Affected Products: Conext™ ComBox (All Versions)

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

This is a clickjacking vulnerability where the Conext ComBox web interface lacks proper X-Frame-Options or Content-Security-Policy frame-ancestors headers, allowing the application to be embedded in iframes on external websites. An attacker could overlay the legitimate interface with invisible or disguised elements to trick administrators into performing unintended actions such as configuration changes or credential submissions.

MitigationAdd X-Frame-Options: DENY or SAMEORIGIN header and/or Content-Security-Policy with frame-ancestors directive to prevent the application from being rendered in iframes on unauthorized domains.

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. Access the web interface HTTP headers
    Send an HTTP GET request to the Conext Combox web interface (typically on port 80/443) and inspect all response headers returned by the server
    Affected if The response lacks both X-Frame-Options header and Content-Security-Policy header containing frame-ancestors directive
  2. Verify X-Frame-Options header presence
    Search the HTTP response headers for 'X-Frame-Options' - check for values such as DENY, SAMEORIGIN, or an allowed origin list
    Affected if The X-Frame-Options header is missing from all web interface responses
  3. Verify Content-Security-Policy frame-ancestors
    Search the HTTP response headers for 'Content-Security-Policy' and check if it contains the 'frame-ancestors' directive
    Affected if The CSP header is missing or does not include frame-anchestors directive to restrict iframe embedding
  4. Test iframe embedding capability
    Create a test HTML page with an iframe pointing to the Conext Combox web interface URL and attempt to load it from a different domain
    Affected if The page loads successfully in the iframe without being blocked by browser security restrictions

The device is affected if the web interface responses do not include X-Frame-Options or Content-Security-Policy with frame-ancestors directive, allowing the interface to be embedded in iframes on external websites.
