AI-suggested

Users should upgrade to Apache Artemis version 2.57.0, which contains the fix for this vulnerability. No other mitigation or temporary workaround is indicated.

Description

When the broker is processing message-based management requests, sent by an authenticated messaging client that is authorized with MANAGE permission to perform management-via-messaging, the parameter processing can trigger Java deserialization of certain method parameters that the broker will not utilise. The permitted types allow to craft a payload causing excessive computation and pinning the processing thread, leading to denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.3.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.

Impact

An authenticated and authorized messaging client can cause a denial of service by sending specially crafted management requests that trigger excessive computation and thread pinning in the broker. This disrupts normal broker operations by exhausting processing resources.
