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
nessusd_www_server.nbin in the Nessus Web Server plugin 1.2.4 for Nessus allows remote attackers to obtain sensitive information via a request to the /feed method, which reveals the version in a response.

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 Nessus Web Server plugin 1.2.4 contains an information disclosure vulnerability where the /feed HTTP method returns the Nessus version in the response header or body. This allows remote unauthenticated attackers to fingerprint the exact Nessus installation version, potentially enabling targeted attacks against known vulnerabilities in that specific version.

MitigationUpdate the Nessus Web Server plugin to a version that does not disclose version information, or implement web server configuration controls to suppress version banners in HTTP responses.

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 Nessus Web Server Plugin version
    Locate the Nessus installation and check the installed plugin version. On Nessus installations, the plugin version is typically found in the plugin directory or can be retrieved via the Nessus web interface under 'Plugin Information' or through the plugin feed metadata.
    Affected if The installed Nessus Web Server Plugin version is exactly 1.2.4
  2. Verify /feed endpoint accessibility
    Send an HTTP GET request to the /feed endpoint on the Nessus web server. This is typically accessed via: http://[nessus-host]:8834/feed or https://[nessus-host]:8834/feed
    Affected if The /feed endpoint responds with HTTP 200 OK and returns content
  3. Check response for version disclosure
    Examine the HTTP response headers and body from the /feed request. Look for any Nessus version strings, build numbers, or product identification information in the headers (such as Server header) or in the response body (XML, JSON, or plain text content).
    Affected if The response header or body contains the Nessus version number (any version string) or build information

You are affected if the Nessus Web Server Plugin version 1.2.4 is installed AND the /feed endpoint is accessible and returns version information in the HTTP response.
