Descriptions

Internet Explorer 5.01 through 6 SP1 allows remote attackers to spoof the domain of a URL via a "%01" character before an @ sign in the user@domain portion of the URL, which hides the rest of the URL, including the real site, in the address bar, aka the "Improper URL Canonicalization Vulnerability."

Internet Explorer 6 y posiblemente otras versiones, permite a atacantes remotos suplantar el dominio de una URL mediante un carácter "%01" antes de un carácter "@" (arroba) en la porción usario@dominio de la URL, lo que esconde el resto de la URL, incluyendo el sitio real, en la barra de direcciones.
