Descriptions

The Apache HTTP Server in Apple OS X before 10.12 and OS X Server before 5.2 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted CGI client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue, a related issue to CVE-2016-5387.

El Apache HTTP Server en Apple OS X en versiones anteriores a 10.12 y OS X Server en versiones anteriores a 5.2 sigue a la sección 4.1.18 del RFC 3875 y por lo tanto no protege aplicaciones de la presencia de datos de cliente CGI no confiables en el entorno variable HTTP_PROXY, lo que podría permitir a atacantes remotos redireccionar el tráfico HTTP fuera de rango de una aplicación a un servidor proxy arbitrario a través de una cabecera Proxy manipulada en una petición HTTP, problema también conocido como "httpoxy", un problema relacionado con CVE-2016-5387.
