It was found that the Karaf container used by Red Hat JBoss Fuse 6.x, and Red Hat JBoss A-MQ 6.x, deserializes objects passed to MBeans via JMX operations. An attacker could use this flaw to execute remote code on the server as the user running the Java Virtual Machine if the target MBean contain deserialization gadgets in its classpath.

Description Jason Shepherd 2016-11-15 05:29:53 UTC
It was found that Karaf deserializes objects passed to certain MBeans via the JMX endpoint. An attacker could use this flaw to execute remote code on the server as the user running the Java Virtual Machine.

In order to exploit this issue you need to have credentials of a user with the 'admin' role. Therefore a good mitigation against this attack is to set a strong password for any user with the 'admin' role in the 'etc/users.properties' file of the Red Hat JBoss Fuse 6, or Red Hat JBoss AM-Q 6.

Updated it to amq-6. However seems amq-6.3.0 was valid to me. Maybe you didn't have the latest product.ini?

Which MBeans are affected?
