RMI Rebind Vulnerability in Apache Cassandra Affects User Credential Security

CVE-2020-13946

What is CVE-2020-13946?

In Apache Cassandra, various versions prior to 2.1.22, 2.2.18, 3.0.22, 3.11.8, and 4.0-beta2, a local attacker can exploit the RMI registry to conduct a man-in-the-middle attack. This vulnerability allows the attacker to capture user credentials—including usernames and passwords—used for accessing the JMX interface. Once the attacker has these credentials, they can perform unauthorized operations within the system. It is also critical to note that the JRE vulnerability identified in CVE-2019-2684 can facilitate this exploit remotely.
