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
OpenDaylight Karaf 0.6.1-Carbon fails to clear the cache after a password change, allowing the old password to be used until the Karaf cache is manually cleared (e.g. via restart).

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

OpenDaylight Karaf 0.6.1-Carbon caches user credentials in memory and fails to invalidate cached authentication tokens when a password is changed. This allows the old password to remain valid for authentication until the Karaf cache is manually cleared (e.g., via restart), creating an authentication bypass window.

MitigationAfter any password change in OpenDaylight Karaf, restart the Karaf instance or manually clear the cache to invalidate old credentials. Consider implementing automated credential invalidation on password change or upgrading if a patched version is available.

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 Karaf version
    Run 'karaf --version' or check the Karaf manifest/version file in the installation directory. Common locations: /opt/karaf/etc/org.apache.karaf.version or check the version displayed on Karaf console startup.
    Affected if Installed version is exactly 0.6.1-carbon (note: only this specific version is affected, not other Carbon versions or other releases)
  2. Verify password change activity
    Review Karaf audit logs or authentication system logs for recent password modification events. Check /opt/karaf/data/log/*.log or the Karaf console audit trail if enabled.
    Affected if A password change was performed on any user account since the last Karaf restart
  3. Check authentication cache state
    Inspect the Karaf JAAS authentication configuration in /opt/karaf/etc/org.ops4j.pax.web.cfg or similar JAAS configuration files. Look for cached authentication realms.
    Affected if JAAS realm with credential caching is configured and a password was changed without restarting Karaf
  4. Test old credential validity
    Attempt authentication using the old password for a user account that had its password changed. This requires knowing the previous password.
    Affected if Old password still successfully authenticates after a password change without Karaf restart

You are affected if running OpenDaylight Karaf exactly version 0.6.1-carbon and any user password was changed without restarting the Karaf instance, allowing the old password to remain valid.
