CVE-2009-2816

Estado: ModificadaMedia (6.8)—

La implementación de Cross-Origin Resource Sharing (CORS) en WebKit, tal como es usado en Safari de Apple anterior a versión 4.0.4 y Chrome de Google anterior a versión 3.0.195.33, incluye ciertos encabezados HTTP personalizados en la petición OPTIONS durante operaciones entre orígenes con comprobación previa, lo que facilita a los atacantes remotos conducir ataques de tipo cross-site request forgery (CSRF) por medio de una página web especialmente diseñada.

CVSS
