high Nessus Plugin ID 339366

Language:

Synopsis

The remote host contains a threat prevention, detection, and response platform that is affected by an incorrect authorization vulnerability.

Description

The version of Wazuh Server on the remote host is 4.9.0 prior to 4.10.4, or 4.11.0 prior to 4.14.6. It is, therefore, affected by an incorrect authorization vulnerability:

- PUT /security/users/{user_id} passes request.get('user') instead of request.context['token_info']['sub'] as current_user. An authenticated user with the users_admin role can overwrite the password of protected administrator accounts and gain full administrative control. (CVE-2026-41424)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Wazuh Server version 4.10.4 or 4.14.6 or later.
