Descriptions

SChannel in Microsoft Internet Explorer 6 through 11 does not ensure that a server's X.509 certificate is the same during renegotiation as it was before renegotiation, which allows man-in-the-middle attackers to obtain sensitive information or modify TLS session data via a "triple handshake attack," aka "TLS Server Certificate Renegotiation Vulnerability."

SChannel en Microsoft Internet Explorer 6 hasta 11 no asegura que el certificado X.509 de un servidor sea el mismo durante la renegociación que era antes de la renegociación, lo que permite a atacantes man-in-the-middle obtener información sensible o modificar datos de la sesión TLS a través de un 'ataque de negociación triple,' también conocido como 'Vulnerabilidad de Renegociación del Certificado del Servidor TLS.'
