Descriptions

Microsoft Internet Explorer 8.0 Beta 2 relies on the XDomainRequestAllowed HTTP header to authorize data exchange between domains, which allows remote attackers to bypass the product's XSS Filter protection mechanism, and conduct XSS and cross-domain attacks, by injecting this header after a CRLF sequence, related to "XDomainRequest Allowed Injection (XAI)." NOTE: the vendor has reportedly stated that the XSS Filter intentionally does not attempt to "address every conceivable XSS attack scenario."

Microsoft Internet Explorer 8.0 Beta 2 confía en la cabecera HTTP XDomainRequestAllowed para autorizar el intercambio de datos entre dominios, o que permite a atacantes remotos evitar el mecanismo de protección del producto XSS Filter y dirigir ataques XSS (ejecución de secuencias de comandos en sitios cruzados) y de dominios cruzados, mediante la inyección de esta cabecera después de una secuencia CRLF, relacionado con "XDomainRequest Allowed Injection (XAI)." NOTA: El fabricante mantiene que el filtro XSS de manera intencionada no intenta "abordar todas las hipótesis de ataque XSS".
