Summary
In Apache Cassandra, all versions prior to 2.1.22, 2.2.18, 3.0.22, 3.11.8 and 4.0-beta2, 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.
