CVE-2014-1770

Estado: ModificadaAlta (9.3)—💥 Exploit

Vulnerabilidad de uso después de liberación en Microsoft Internet Explorer 8 permite a atacantes remotos ejecutar código arbitrario a través de código JavaScript manipulado que no interactúa debidamente con una llamada de la función CollectGarbage function en un objeto CMarkup asignado por la función CMarkup::CreateInitialMarkup.

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.
