Published Nov 18, 2019

CRITICALCVSS 3.1
EPSS 21.45%
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.

Remediation
Red Hat mitigation
Per Solr guidance: "Make sure your effective solr.in.sh file has ENABLE_REMOTE_JMX_OPTS set to 'false' on every Solr node and then restart Solr. Note that the effective solr.in.sh file may reside in /etc/defaults/ or another location depending on the install. You can then validate that the 'com.sun.management.jmxremote*' family of properties are not listed in the "Java Properties" section of the Solr Admin UI, or configured in a secure way. There is no need to upgrade or update any code."
