Echo: org.apache.zookeeper:zookeeper: security update to 3.9.2

medium Tenable Cloud Security Plugin ID 457902

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Information disclosure in persistent watchers handling in Apache ZooKeeper due to missing ACL check. It
 allows an attacker to monitor child znodes by attaching a persistent watcher (addWatch command) to a
 parent which the attacker has already access to. ZooKeeper server doesn't do ACL check when the persistent
 watcher is triggered and as a consequence, the full path of znodes that a watch event gets triggered upon
 is exposed to the owner of the watcher. It's important to note that only the path is exposed by this
 vulnerability, not the data of znode, but since znode path can contain sensitive information like user
 name or login ID, this issue is potentially critical. Users are recommended to upgrade to version 3.9.2,
 3.8.4 which fixes the issue. (CVE-2024-23944)

Solution

Update the org.apache.zookeeper:zookeeper library and its related packages to version 3.9.2 or later.
