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 UI in Rapid7 Metasploit before 4.14.1-20170828 allows logout CSRF, aka R7-2017-22.

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 Metasploit Framework web UI before version 4.14.1-20170828 contains a Cross-Site Request Forgery (CSRF) vulnerability in the logout functionality. An attacker could craft a malicious page that, when visited by an authenticated user, would silently force that user's session to terminate via the logout endpoint without their consent or knowledge.

MitigationImplement anti-CSRF token validation on the logout action (require valid token for POST requests to /logout), consistent with the application's existing authentication security model. This is a standard web security fix using Rails built-in csrf_meta_tags and verify_authenticity_token.

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. Determine installed Metasploit Framework version
    Launch msfconsole and run the 'version' command, or check the installed package version via system package manager
    Affected if version is 4.14.1 or lower (any version up to and including 4.14.1)
  2. Verify web UI is enabled and accessible
    Confirm the Metasploit web interface (Web UI or Express) is configured and running - typically accessible via browser on configured port
    Affected if web UI is enabled and accessible to network users
  3. Inspect logout endpoint for CSRF protection
    Examine the logout action code in the Metasploit web UI source - check if verify_authenticity_token is present in the logout controller action, or inspect POST /logout requests for csrf token in headers
    Affected if logout action lacks anti-CSRF token validation (no verify_authenticity_token or token not required for POST requests)
  4. Test logout endpoint behavior
    Send a POST request to /logout without an X-CSRF-Token header or authenticity_token parameter - observe if logout succeeds without token
    Affected if logout completes successfully without requiring valid CSRF token

You are affected if your Metasploit Framework version is 4.14.1 or lower AND the web UI is enabled, and the logout endpoint does not enforce CSRF token validation.
