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
2N Access Commander version 3.4.2 and prior improperly invalidates session tokens, allowing multiple session cookies to remain active after logout in web application.

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

2N Access Commander versions 3.4.2 and prior fail to invalidate session tokens upon logout, allowing multiple session cookies to remain valid after a user terminates their session. This session management flaw enables attackers with access to old session cookies to hijack authenticated sessions even after legitimate logout.

MitigationUpgrade to a version beyond 3.4.2 that properly invalidates server-side session state on logout, and rotate any potentially compromised session tokens.

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 installed version
    Locate the version number of 2N Access Commander in the product's web interface, about section, or system information panel. Compare this against the affected range: versions prior to 3.5 (including 3.4.2 and earlier).
    Affected if The installed version is 3.4.2 or any version lower than 3.5
  2. Test session validity after logout
    Authenticate to the system and obtain a session cookie. Then terminate the session through the logout function. Attempt to use the previously obtained session cookie to access the system.
    Affected if The old session cookie remains valid and grants access after logout has been completed
  3. Verify server-side session state clearing
    Review system logs or session management configuration to determine whether server-side session state is invalidated when a user logs out. Check if session tokens are removed from server-side storage.
    Affected if Server-side session state is not cleared upon logout, allowing old session cookies to continue working

A user is affected if their 2N Access Commander version is 3.4.2 or prior and session cookies remain functional after logout.
