CVE-2016-0050

Estado: ModificadaMedia (5.3)—

Network Policy Server (NPS) en Microsoft Windows Server 2008 SP2 y R2 SP1 y Server 2012 Gold y R2 no analiza correctamente la gramática de las peticiones de nombre de usuario, lo que permite a atacantes remotos causar una denegación de servicio (interrupción de autenticación RADIUS) a través de peticiones manipuladas, también conocida como "Network Policy Server RADIUS Implementation Denial of Service Vulnerability".

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).
