AI-suggested
Users should upgrade to Apache Artemis version 2.57.0 or later, which fixes this vulnerability. No other mitigation or temporary fix is indicated in the available data.
Description
An unauthenticated network-adjacent attacker can leverage discovery to capture cluster administrative credentials during the initial cluster connection handshake. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.
Impact
An unauthenticated attacker can obtain cluster administrative credentials, potentially allowing unauthorized access to cluster administrative functions. This could lead to unauthorized control or disruption of the cluster. The vulnerability affects multiple versions of Apache Artemis and Apache ActiveMQ Artemis prior to 2.57.0.
