Official Description

Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 3.9.0 and prior to version 4.14.3, a privilege escalation vulnerability exists in the Wazuh Manager's cluster synchronization protocol. The `wazuh-clusterd` service allows authenticated nodes to write arbitrary files to the manager’s file system with the permissions of the `wazuh` system user. Due to insecure default permissions, the `wazuh` user has write access to the manager's main configuration file (`/var/ossec/etc/ossec.conf`). By leveraging the cluster protocol to overwrite `ossec.conf`, an attacker can inject a malicious `<localfile>` command block. The `wazuh-logcollector` service, which runs as root, parses this configuration and executes the injected command. This chain allows an attacker with cluster credentials to gain full Root Remote Code Execution, violating the principle of least privilege and bypassing the intended security model. Version 4.14.3 fixes the issue.

Technical Analysis

CVE-2026-25770 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.2.
