Descriptions

The implementation of Cross-Origin Resource Sharing (CORS) in WebKit, as used in Apple Safari before 4.0.4 and Google Chrome before 3.0.195.33, includes certain custom HTTP headers in the OPTIONS request during cross-origin operations with preflight, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via a crafted web page.

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.
