CVE-2008-1545

Estado: ModificadaMedia (4.3)—

El método setRequestHeader del objeto XMLHttpRequest en Microsoft Internet Explorer 7 no restringe las cabeceras de las peticiones HTTP Transfer-Encoding peligrosas, lo que permite a atacantes remotos llevar a cabo ataques de división y contrabando de peticiones HTTP mediante un POST que contiene una cabecera "Transfer-Encoding: chunked" y un contenido con un tamaño de trozo incorrecto.
