Apache ZooKeeper 3.9.x < 3.9.4 Improper Permission Check

medium Nessus Plugin ID 301977

Synopsis

The remote Apache ZooKeeper server is affected by an improper permission check vulnerability.

Description

The version of Apache ZooKeeper listening on the remote host is 3.9.x prior to 3.9.4. It is, therefore, affected by an improper permission check vulnerability:

- Improper permission check in ZooKeeper AdminServer lets authorized clients to run snapshot and restore commands with insufficient permissions. The issue can be mitigated by disabling both commands (via admin.snapshot.enabled and admin.restore.enabled), disabling the whole AdminServer interface (via admin.enableServer), or ensuring that the root ACL does not provide open permissions. (CVE-2025-58457)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update to Apache ZooKeeper 3.9.4 or later.
