Описание
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.
A flaw was found in the Apache Zookeeper package. Affected versions of this package are vulnerable to Information Exposure due to a missing ACL check in the handling of persistent watchers. An attacker can monitor child znodes by attaching a persistent watcher (addWatch command) to a parent node that the attacker has access to. The server does not perform an ACL check when the persistent watcher is triggered, exposing the full path of znodes to the owner of the watcher.
Отчет
Only the path is exposed by this vulnerability, not the data in the znode. Since the znode path may contain sensitive information such as usernames or login IDs, the impact on confidentiality is "High".
