CVE-2020-13946: Infoleak
A flaw was found in cassandra in versions prior to 2.1.22, 2.2.18, 3.0.22, 3.11.8 and 4.0-beta2. A local attacker without access to the Apache Cassandra process or configuration files can manipulate the RMI registry to perform a man-in-the-middle attack and capture user names and passwords used to access the JMX interface. A JRE vulnerability (CVE-2019-2684) enables this issue to be exploited remotely. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
