Apache ZooKeeper 3.9.x < 3.9.3 Authentication Bypass

critical Nessus Plugin ID 210584

Language:

Synopsis

The remote Apache ZooKeeper server is affected by an authentication bypass vulnerability.

Description

The version of Apache ZooKeeper listening on the remote host is 3.9.x prior to 3.9.3. It is, therefore, affected by an authentication bypass vulnerability:

 - When using IPAuthenticationProvider in ZooKeeper Admin Server there is a possibility of Authentication Bypass by Spoofing -- this only impacts IP based authentication implemented in ZooKeeper Admin Server. Default configuration of client's IP address detection in IPAuthenticationProvider, which uses HTTP request headers, is weak and allows an attacker to bypass authentication via spoofing client's IP address in request headers. Default configuration honors X- Forwarded-For HTTP header to read client's IP address. X-Forwarded-For request header is mainly used by proxy servers to identify the client and can be easily spoofed by an attacker pretending that the request comes from a different IP address. Admin Server commands, such as snapshot and restore arbitrarily can be executed on successful exploitation which could potentially lead to information leakage or service availability issues. Users are recommended to upgrade to version 3.9.3, which fixes this issue. (CVE-2024-51504) 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 3.9.3 or later.
