CVE-2017-8661

Estado: ModificadaAlta (7.5)—

Microsoft Edge en Microsoft Windows 10 1607, 1703, y Windows Server 2016 permite que un atacante ejecute código arbitrario en el contexto del usuario actual debido a la forma en la que los motores Microsoft scripting afectados renderizan cuando gestionan objetos en la memoria. Esto también se conoce como "Vulnerabilidad de corrupción de memoria en Microsoft Edge".

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).
