"The version of Apache Solr running on the remote web server is affected by a remote code execution vulnerability in the
Config API due to unsafe deserialization of Java objects. An unauthenticated, remote attacker can exploit this, via an
HTTP POST request that points the JMX server to a  malicious RMI server. An attacker could then send a crafted
serialized Java object to the server, to execute arbitrary code.");
