Apache ZooKeeper: Sensitive information disclosure in client configuration handling
Overview
Description
Improper handling of configuration values in ZKConfig in Apache ZooKeeper 3.8.5 and 3.9.4 on all platforms allows an attacker to expose sensitive information stored in client configuration in the client's logfile. Configuration values are exposed at INFO level logging rendering potential production systems affected by the issue. Users are recommended to upgrade to version 3.8.6 or 3.9.5 which fixes this issue.

Solution
Upgrade Apache ZooKeeper to a patched version to prevent sensitive information exposure.
- Upgrade Apache ZooKeeper to version 3.8.6 or 3.9.5.
- Review client log files for exposed sensitive information.
- Restrict access to log files.
- Apply secure configuration settings.
