  "details" : [ "A flaw was found in Apache ActiveMQ. An authenticated attacker can bypass a previous security fix by adding a connector using an HTTP Discovery transport through Jolokia, if the activemq-http module is present. A malicious HTTP endpoint can return a virtual machine (VM) transport, which allows the attacker to load a remote Spring XML application context. This can lead to arbitrary code execution on the broker's Java Virtual Machine (JVM)." ],
