Descriptions

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.

Apache Cassandra versiones 2.1.0 hasta 2.1.22, versiones 2.2.0 hasta 2.2.19, versiones 3.0.0 hasta 3.0.23 y versiones 3.11.0 hasta 3.11.9, cuando se usa la configuración internode_encryption de "dc" o "rack", permite ambas conexiones de entre nodo cifradas y no cifradas. Un nodo configurado inapropiadamente o un usuario malicioso pueden usar la conexión no cifrada a pesar de no estar en el mismo rack o dc y omitir el requisito mutuo de TLS
