Summary

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. Artemis and JGroups lack of access controls in certain situations can allow an attacker to spoof a password request in JGroups and subsequently gain access to the cluster.

This allows the attacker manage-level authority for provided messaging and queue operations. Red Hat severity: Important — CVSS 8 (CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

Affected Red Hat products: Red Hat AMQ Broker 7.13.6; Red Hat AMQ Broker 7.14.1; Red Hat JBoss Enterprise Application Platform 7.4.25; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 8; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 9; Red Hat JBoss Enterprise Application Platform 8.1; Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 10; Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 8; Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 9; Red Hat JBoss Enterprise Application Platform 7; Red Hat JBoss Enterprise Application Platform 8.
