application running on the remote host is 3.1.x prior to 3.1.6.7959.
It is, therefore, affected by a remote code execution vulnerability in
the JMXInvokerServlet interface due to improper validation of Java
objects before deserialization. An authenticated, remote attacker can
exploit this to execute arbitrary code. (CVE-2015-7501)");
