The (1) HttpResource and (2) FileBackedHttpResource implementations in Shibboleth Identity Provider (IdP) before 2.4.1 and OpenSAML Java 2.6.2 do not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Las implementaciones de (1) HttpResource y (2) FileBackedHttpResource en el Proveedor de Identidad (IdP) de Shibboleth, en versiones anteriores a la 2.4.1, y en OpenSAML Java, en su versión 2.6.2, no verifican que el nombre de host del servidor se corresponda con un nombre de dominio en el campo "Common Name" (CN) del asunto o en el campo "subjectAltName" del certificado X.509. Esto permite a los atacantes Man-in-the-Middle (MitM) suplantar los servidores SSL a través de un certificado arbitrario válido.
