CVE-2026-44252

Estado: AnalizadaAlta (7.7)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:L permite T1210 (servicio remoto con privilegios bajos). El atacante suplanta workers para obtener acceso de administrador (T1078), crear cuentas (T1098) y modificar configuración RBAC (T1556).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
