Summary

A logic flaw in Wazuh Manager versions 4.0.0-4.10.3 and 4.11.0-4.14.4 affects the enrollment daemon (authd) and synchronization daemon (remoted). The authd process allows agents to select a group during enrollment without filtering path traversal sequences like "..", enabling access to files outside the intended directory. Sensitive files such as client.keys, ossec.conf, and internal certificates are exposed to the attacker.

Risk Assessment

An attacker can access sensitive configuration and authentication data of the Wazuh Manager, potentially leading to compromise of the security monitoring platform and further attacks on IT infrastructure.

Recommendation

Immediately upgrade Wazuh Manager to version 4.10.4 or 4.14.5, which fix this vulnerability. Before upgrading, consider restricting trust for registered agents and monitoring logs for suspicious group names.

Original NVD description (English source)

Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 4.0.0 through 4.10.3 and 4.11.0 through 4.14.4, a logic flaw affects the Wazuh Manager's enrollment daemon (authd) and synchronization daemon (remoted). The authd process allows agents to select a group during enrollment but does not filter path traversal sequences such as "..." While the manager checks for the group directory using wopendir(), the ".." sequence references the parent directory (/var/ossec/etc), allowing it to pass validation. After the malicious group is accepted and stored in the manager's global database, the remoted process uses this unchecked value to build paths for agent configuration synchronization. As a result, sensitive files from /var/ossec/etc, such as client.keys, ossec.conf, and internal certificates, are included in the agent's shared configuration stream and exposed to the attacker. This issue has been fixed in versions 4.10.4 and 4.14.5.
