Summary
Wazuh 4.0.0 through 4.14.6 contains a path traversal vulnerability that allows authenticated cluster peers to delete arbitrary directory contents by supplying a traversal-shaped node name in the cluster hello payload without validation. Attackers holding a valid cluster Fernet key can craft a malicious node name and disconnect, triggering the master's peer cleanup routine to remove the contents of arbitrary directories within the Wazuh installation path writable by the wazuh user.
Risk Assessment
The risk includes unauthorized deletion of files and directories within the Wazuh installation, potentially leading to data loss, service disruption, or privilege escalation.
Recommendation
It is recommended to immediately upgrade Wazuh to version 4.14.6 or later and restrict trust in cluster peers and Fernet keys.
