So unless this has been manually disabled, every Fuse 6 system is affected by this vulnerability.\n\n\n* How to determine if a Fuse 7 system is affected:\nFuse 7 itself is not vulnerable. By default it ships the vulnerable activemq-client jar, however it does not instantiate an ActiveMQ broker. If this feature (connect to an external ActiveMQ Broker) were manually configured, it would make it vulnerable.\n\n\n* How to determine if a Fuse Online system is affected:\nSyndesis,  an Integration Platform As A Service part of Fuse Online which runs on top of Openshift, does not use activemq code. Also, it doesn\u0027t instantiate a broker with Openwire protocol enabled, which makes it not vulnerable to this CVE.",
