CVE-2025-50171

Estado: AnalizadaCrítica (9.1)—

Missing authorization in Remote Desktop Server allows an unauthorized attacker to perform spoofing over a network.

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.

Vector de red sin autenticación (AV:N/PR:N/UI:N) y falta de autorización (CWE-862) en RDS permiten acceso no autorizado remoto; suplantación de identidad (spoofing) implica obtención/abuso de credenciales o cuentas.

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.
