Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
