CVE-2007-3164

Estado: ModificadaMedia (5.8)—

Microsoft Internet Explorer 7, cuando se avisa a HTTP Basic Authentication para un sitio web IDN, utiliza etiquetas ACE para el nombre de dominio en la barra de estado, pero utiliza etiquetas internacionalizadas para este nombre en diálogo de validación, lo cual podría permitir a un atacante remoto realizar ataques de phishing si el usuario malinterpreta caracteres confusos en las etiquetas internacionales, como se demostró exhibiendo xn--theshmogroup-bgk.com solo en la barra de estado.
