Apache Zookeeper x < 3.4.10 / 3.5.x < 3.5.4 Missing Authentication Remote Quorum Joining Vulnerability

high Nessus Plugin ID 110266

Synopsis

The remote Apache Zookeeper server is prone to a quorum joining attack.

Description

The instance of Apache Zookeeper listening on the remote host is either running a version that does not support quorum authentication or has not been configured to use quorum authentication. This may allow a remote attacker to join a cluster quorum and begin propagating counterfeit changes to the leader.

Solution

Update to Apache Zookeeper 3.4.10 or 3.5.4 or later and enable Quorum Peer mutual authentication.
