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.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

1.3.0 ≤ v ≤ 2.44.01.3.0 ≤ v < 2.44.02.50.0 ≤ v ≤ 2.56.02.50.0 ≤ v < 2.57.01.3.02.50.0
Affected range stops below 2.44.0, so it looks safe — our inference, not a vendor statement
Affected range stops below 2.57.0, so it looks safe — our inference, not a vendor statement
