CVE-2014-1766

Estado: ModificadaAlta (9.3)—💥 Exploit

Microsoft Internet Explorer 9 hasta la versión 11 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, según lo demostrado por Sebastian Apelt y Andreas Schmidt durante una competición Pwn2Own en CanSecWest 2014. NOTA: la divulgación original se refería al desencadenamiento de un error del kernel explotado con la carga de Internet Explorer, pero este ID no es para una vulnerabilidad del kernel.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
