CVE-2024-51504 (opens in a new tab)How to fix?
Upgrade org.apache.zookeeper:zookeeper to version 3.9.3 or higher.
Overview
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 by Spoofing due to the default configuration of the IPAuthenticationProvider, which relies on HTTP request headers for IP address detection. An attacker can bypass authentication by spoofing the client's IP address in the X-Forwarded-For header. This vulnerability allows unauthorized execution of admin server commands such as snapshot and restore, potentially leading to information leakage or service availability issues.
Note:
This vulnerability only impacts IP-based authentication implemented in ZooKeeper Admin Server.
