From 4.3.0 until 4.14.6 and 5.0.0-beta3, the non-merged branch of process_files_from_worker() in framework/wazuh/core/cluster/master.py trusts a peer-controlled file_path key from files_metadata.json. The destination is joined to WAZUH_PATH without proving that it remains inside the directory selected by cluster_item_key. 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.\n\n## Affected\n\n- `wazuh >= 4.3.0, < 4.14.6`\n- `wazuh = 5.0.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `wazuh 4.14.6`","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":50.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
