Description Sam Fowler 2018-05-23 04:02:15 UTC
Apache ZooKeeper before 3.4.10, and 3.5.0-alpha through 3.5.3-beta does not enforce any authentication/authorization when a server attempts to join a quorum. As a result an arbitrary end point could join the cluster and begin propagating counterfeit changes to the leader.

Comment 1 Sam Fowler 2018-05-23 04:03:00 UTC
Created zookeeper tracking bugs for this issue:

Affects: fedora-all [bug 1581543]

Comment 4 Jason Shepherd 2018-05-23 06:25:13 UTC
Zookeeper is also included in vertx as a dependency of the vertx-kafka component. Setting it back to new while we investigate it it's affected or not.

Comment 5 Jason Shepherd 2018-05-23 07:14:28 UTC
vertx-kafka-client is a component which allows vertx to talk to a kafka instance. It does not actually use zookeeper itself to form a quorom. Setting as NOTAFFECTED. ref:

Comment 6 Hooman Broujerdi 2018-05-23 23:32:28 UTC
Statement:

Zookeeper is not designed to run as a publicly available service and it always needs to be deployed and operated in a secured environment. As a result it is assumed that no zookeeper ports are available publically, so with this assumption JBoss Fuse is not affected by this issue.
