CVE-2008-3473

Estado: ModificadaAlta (9.3)—

Microsoft Internet Explorer v6 y v7 no determina de forma adecuada el dominio o zona de seguridad del origen de la secuencia de comandos web, lo que permite a atacantes remotos saltar la política de seguridad de dominios cruzados implementada, y ejecutar código arbitrario u obtener información sensible mediante un documento HTML modificado, también conocido como "vulnerabilidad de dominios cruzados en el manejo de eventos".

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).
