Descriptions

yaws before 2.0.4 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue.

yaws versiones anteriores a la versión 2.0.4, no intenta abordar los conflictos de espacio de nombres de RFC sección 3875 versión 4.1.18 y, por lo tanto, no protege las aplicaciones CGI de la presencia de datos de clientes no seguros en la variable de entorno HTTP_PROXY, lo que podría permitir a atacantes remotos redireccionar el tráfico HTTP saliente de la aplicación CGI hacia un servidor proxy arbitrario por medio de un encabezado Proxy especialmente diseñado en una petición HTTP, también se conoce como un problema "httpoxy".
