    Authorization Bypass Through User-Controlled Key

    org.apache.zookeeper:zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.

    Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key when the SASL Quorum Peer authentication is enabled (`quorum.auth.enableSasl=true), an attacker can bypass the authorization check by omitting the instance part in the SASL authentication ID. This allows an arbitrary endpoint to join the cluster and propagate counterfeit changes to the leader, effectively granting it full read-write access to the data tree.

    Note:

    1. This is only exploitable if quorum.auth.enableSasl=true is set in the configuration.

    2. Quorum Peer authentication is not enabled by default.

    How to fix Authorization Bypass Through User-Controlled Key?

    Upgrade org.apache.zookeeper:zookeeper to version 3.7.2, 3.8.3, 3.9.1 or higher.

    Access Control Bypass

    org.apache.zookeeper:zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.

    Affected versions of this package are vulnerable to Access Control Bypass. ZooKeeper’s getACL() method doesn’t check any permission when retrieving the ACLs of the requested node and returns all information contained in the ACL Id field as plain text string. If Digest Authentication is in use, the unsalted hash value will be disclosed by the getACL() method for unauthenticated or unprivileged users.

    How to fix Access Control Bypass?

    Upgrade org.apache.zookeeper:zookeeper to version 3.4.14, 3.5.5 or higher.

    Authentication Bypass

    org.apache.zookeeper:zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.

    Affected versions of this package are vulnerable to Authentication Bypass. No authentication/authorization is enforced 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.

    How to fix Authentication Bypass?

    Upgrade org.apache.zookeeper:zookeeper to version 3.4.10, 3.5.4-beta or higher.

    Denial of Service (DoS)

    org.apache.zookeeper:zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.

    Affected versions of this package are vulnerable to Denial of Service (DoS). Four letter zookeeper commands (such as wchp/wchc ) are not properly handled, which leads to the server unable to serve legitimate client requests.

    How to fix Denial of Service (DoS)?

    Upgrade org.apache.zookeeper:zookeeper to version 3.4.10, 3.5.3-beta or higher.
