Authentication Bypass by Spoofing


Severity High
Score 7.5/10


Apache Cassandra versions before 3.0.24, 3.1.0 to 3.11.9, and 4.x through 4.0-beta3 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.
