Reason: Fixes CVE-2020-13946 Apache Cassandra RMI Rebind Vulnerability
Description:
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.
2.1.x users should upgrade to 2.1.22
