Descriptions

The default configuration of SGOS in Blue Coat ProxySG before 6.2.16.5, 6.5 before 6.5.7.1, and 6.6 before 6.6.2.1 forwards authentication challenges from upstream origin content servers (OCS) when used in an explicit proxy deployment, which makes it easier for remote attackers to obtain sensitive information via a 407 (aka Proxy Authentication Required) HTTP status code, as demonstrated when using NTLM authentication.

La configuración por defecto de SGOS en Blue Coat ProxySG en versiones anteriores a 6.2.16.5, 6.5 en versiones anteriores a 6.5.7.1 y 6.6 en versiones anteriores a 6.6.2.1 reenvía retos de autenticación desde los servidores de contenido de origen (OCS) de subida cuando se usa en el despliegue de un proxy explícito, lo que hace más fácil para atacantes remotos obtener información sensible a través de un código de estado HTTP 407 (también conocido como Proxy Authentication Required), según lo demostrado cuando se utiliza autenticación NTLM.
