Summary

Wazuh : peer-controlled metadata key in process_files_from_worker non-merged branch allows arbitrary file write under WAZUH_PATH on Wazuh manager

Details

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.3.0 until 4.14.6 and 5.0.0-beta3, the non-merged branch of processfilesfromworker() in framework/wazuh/core/cluster/master.py trusts a peer-controlled filepath key from filesmetadata.json. The destination is joined to WAZUHPATH without proving that it remains inside the directory selected by clusteritemkey. A cluster peer holding the shared Fernet key can upload a crafted extra-valid archive and overwrite security-sensitive files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution after a service reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.
