Description

Default superuser cassandra:cassandra left active when CASSANDRA_USER is customized

Bitnami Cassandra container images are affected by a retained default superuser vulnerability. When a custom administrator account is configured via the CASSANDRA_USER environment variable, the container initialization script creates the new superuser account but fails to drop the built-in cassandra account in certain scenarios. This leaves the default cassandra:cassandra superuser active as an unintended access path. Any remote attacker who knows the default Cassandra credentials, can authenticate to the cluster as a full superuser regardless of the operator's configuration, bypassing the intent to replace the built-in account.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
