A flaw was discovered in Apache Solr, where it contains an insecure setting in the default configuration that exposes unauthenticated access to the JMX monitoring service. This flaw allows an attacker to upload malicious code for execution on the Solr server.

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."
