CVE-2015-0078

Estado: ModificadaAlta (7.2)—

win32k.sys en los controladores de modo de kernel en Microsoft Windows 8, Windows 8.1, Windows Server 2012 Gold y R2, y Windows RT Gold y 8.1 no valida correctamente el token de un hilo de llamada, lo que permite a usuarios locales ganar privilegios a través de una aplicación manipulada, también conocido como 'vulnerabilidad de la elevación de privilegios de Win32k.'

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).
