## Description

The 8.1.1 and 8.2.0 releases of Apache Solr contain an insecure setting for
the ENABLE\_REMOTE\_JMX\_OPTS configuration option in the default solr.in.sh
configuration file shipping with Solr. If you use the default solr.in.sh
file from the affected releases, then JMX monitoring will be enabled and
exposed on RMI\_PORT (default=18983), without any authentication. If this
port is opened for inbound traffic in your firewall, then anyone with
network access to your Solr nodes will be able to access JMX, which may in
turn allow them to upload malicious code for execution on the Solr server.
