CVE-2026-57910

Estado: AplazadaCrítica (9.3)—

Improper authentication in the WatchGuard Agent allows an unauthenticated attacker with network access to cause the agent to execute arbitrary code with elevated privileges.

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:N/UI:N indica red sin autenticación (T1190). CWE-306 (autenticación impropia) + ejecución con privilegios elevados permite autenticación falsa (T1078) y escalada (T1068) con capacidad de ejecutar código arbitrario (T1059).

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.
