CVE-2026-44252

Full vulnerability record from the local CVENow database.

Description

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.5, Wazuh Manager allows a low-privilege read-only API user with manager:read permission to retrieve the cluster key from the element in ossec.conf through GET /manager/configuration?raw=true. An attacker with network access to TCP port 1516 can use the disclosed Fernet key to impersonate a cluster worker and submit distributed API requests containing attacker-controlled rbac_permissions with rbac_mode set to black. Because the master trusts the worker-supplied authorization context, the attacker can create users, assign administrator roles, access credentials and API tokens, modify configuration, and execute actions across agents. This issue is fixed in version 4.14.5.

      "value": "Wazuh es una plataforma de código abierto y gratuita utilizada para la prevención, detección y respuesta a amenazas. Desde 4.0.0 hasta 4.14.5, Wazuh Manager permite a un usuario de API de solo lectura con bajos privilegios y permiso manager:read recuperar la clave del clúster del elemento en ossec.conf a través de GET /manager/configuration?raw=true. Un atacante con acceso de red al puerto TCP 1516 puede usar la clave Fernet divulgada para suplantar a un trabajador del clúster y enviar solicitudes de API distribuidas que contengan rbac_permissions controlados por el atacante con rbac_mode establecido en black. Debido a que el maestro confía en el contexto de autorización proporcionado por el trabajador, el atacante puede crear usuarios, asignar roles de administrador, acceder a credenciales y tokens de API, modificar la configuración y ejecutar acciones en todos los agentes. Este problema está solucionado en la versión 4.14.5."
