How to fix?

Upgrade org.apache.cassandra:cassandra-all to version 2.1.22, 2.2.18, 3.0.22, 3.11.8, 4.0-beta2 or higher.


org.apache.cassandra:cassandra-all is a maven plugin for the Apache Cassandra Project. Which, develops a highly scalable second-generation distributed database, bringing together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model.

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM). It is possible for a local attacker without access to the Apache Cassandra process or configuration files to manipulate the RMI registry to perform a man-in-the-middle attack and capture user names and passwords used to access the JMX interface. The attacker can then use these credentials to access the JMX interface and perform unauthorised operations. Users should also be aware of CVE-2019-2684, a JRE vulnerability that enables this issue to be exploited remotely.
