This vulnerability is classified as Improper Authentication (CWE-287), which allows attackers to bypass authentication mechanisms to gain unauthorized access. In Apache Cassandra 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 unauthorized operations. This is same vulnerability that CVE-2020-13946 was issued for, but the Java option was changed in JDK10.0.2 through 5.0.2 running Java 11. Operators are recommended to upgrade to a release equal to or later than 4.0.15, 4.1.8, or 5.0.3 which fixes the issue. Affected products include: Apache Cassandra. Version information: through 5.0.2.
