CVE-2020-13946 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. 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. EPSS estimates a 2.95% chance of exploitation in the next 30 days.
