Wazuh Server 4.0.0 < 4.14.6 Multiple Vulnerabilities
high Nessus Plugin ID 339367
Language:
Synopsis
The remote host contains a threat prevention, detection, and response platform that is affected by multiple vulnerabilities.Description
The version of Wazuh Server on the remote host is at least 4.0.0 and prior to 4.14.6. It is, therefore, affected by multiple vulnerabilities, including:- cluster.unmerge_info() constructs paths from peer-controlled merge_type and name values in a merged synchronization archive. A cluster peer holding the shared Fernet key can use traversal to write arbitrary files such as ossec.conf, leading to code execution when Wazuh services reload. (CVE-2026-48024)
- DistributedAPI.send_tmp_file() joins an attacker-controlled tmp_file value to WAZUH_PATH without canonicalization. A cluster peer can use traversal to read any file accessible to the master, including the API private key, allowing forged administrator tokens. (CVE-2026-48162)
- AffectedItemsWazuhResult.merge() trusts the sort_casting field in a cluster worker's JSON response. A compromised worker can set sort_casting to exec and place Python source in affected_items, causing the master to execute the payload as root. (CVE-2026-44901)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Wazuh Server version 4.14.6 or later.See Also
