CVE-2018-8339

Estado: ModificadaAlta (7)—

Existe una vulnerabilidad de elevación de privilegios en el instalador de Windows cuando el instalador de Windows no sanea correctamente las entradas, provocando un comportamiento de carga de librerías no seguro. Esto también se conoce como "Windows Installer Elevation of Privilege Vulnerability". Esto afecta a Windows 7, Windows Server 2012 R2, Windows RT 8.1, Windows Server 2008, Windows Server 2012, Windows 8.1, Windows Server 2016, Windows Server 2008 R2, Windows 10 y Windows 10 Servers.

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).
