Description

Apache Cassandra versions 2.1.0 to 2.1.22, 2.2.0 to 2.2.19, 3.0.0 to 3.0.23, and 3.11.0 to 3.11.9, when using 'dc' or 'rack' internode_encryption setting, allows both encrypted and unencrypted internode connections. A misconfigured node or a malicious user can use the unencrypted connection despite not being in the same rack or dc, and bypass mutual TLS requirement.

Affected configurations

• apache cassandra (>= 2.1.0 <= 2.1.22) • apache cassandra (>= 2.2.0 <= 2.2.19) • apache cassandra (>= 3.0.0 <= 3.0.23) • apache cassandra (>= 3.11.0 <= 3.11.9)
