What it is

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta3, cluster.unmerge_info() in framework/wazuh/core/cluster/cluster.py constructs paths from peer-controlled merge_type and name values in a merged synchronization archive. process_files_from_worker() in framework/wazuh/core/cluster/master.py does not adequately confine the resulting path to the declared cluster item directory. A cluster peer holding the shared Fernet key can use traversal in files_metadata.json or a merged-file header to write files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution when Wazuh services reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.
