Updated

The default configuration in Apache Cassandra 3.8 through 3.11.1 binds an unauthenticated JMX/RMI interface to all network interfaces, which allows remote attackers to execute arbitrary Java code via an RMI request. This issue is a regression of CVE-2015-0225. The regression was introduced in https://issues.apache.org/jira/browse/CASSANDRA-12109. The fix for the regression is implemented in https://issues.apache.org/jira/browse/CASSANDRA-14173. This fix is contained in the 3.11.2 release of Apache Cassandra.

Upgrade
Upgrade Apache Cassandra to a version that resolves this vulnerability.
Fixed in 3.11.2Patch CASSANDRA-14173
Compensating control
If upgrading is not immediately possible, restrict network access to the JMX/RMI interface so it is not reachable from untrusted networks (the issue is that Cassandra 3.8 through 3.11.1 binds the unauthenticated JMX/RMI interface to all network interfaces).
