Description

A flaw was found in Apache ActiveMQ Artemis. The JsonUtil.fromJsonArray() method uses ObjectInputStream.readObject() to deserialize CompositeData from Base64-encoded serialized objects in management message bodies sent to the activemq.management address. While the deserialization is protected by an allowlist (java.util,java.lang,javax.management) that blocks RCE gadget chains, an authenticated attacker with the MANAGE role can craft a deserialization bomb using deeply nested java.util.HashSet/HashMap structures to exhaust CPU/memory and crash the broker JVM, causing denial of service for all connected clients.
