CyberRota Analysis
AI-GeneratedWazuh versions 4.3.0 to 4.14.6 and 5.0.0-beta3 are vulnerable due to improper validation of file paths in the process_files_from_worker() function, allowing a malicious cluster peer to overwrite critical configuration files like ossec.conf. This can lead to unauthorized code execution with root privileges upon service reload, posing a significant security risk. Organizations using affected Wazuh versions should prioritize patching to mitigate potential exploitation.

Original NVD Description
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 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.
