Description Guilherme de Almeida Suckevicz 2021-02-02 13:43:06 UTC 
When using ‘dc’ or ‘rack’ internode_encryption setting, a Cassandra instance allows both encrypted and unencrypted 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.
