Descriptions
Varnish 3.x before 3.0.7, when used in certain stacked installations, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a header line terminated by a \r (carriage return) character in conjunction with multiple Content-Length headers in an HTTP request.
Varnish 3.x en versiones anteriores a 3.0.7, cuando se utiliza en ciertas instalaciones apiladas, permite a atacantes remotos inyectar cabeceras HTTP arbitrarias y llevar a cabo ataques de separación de respuesta HTTP a través de una línea de cabecera terminada por un carácter \r (retorno de carro) en conjunción con múltiples cabeceras Content-Length en una petición HTTP.
Regis Leroy from Makina Corpus discovered that varnish, a caching HTTP reverse proxy, is vulnerable to HTTP smuggling issues, potentially resulting in cache poisoning or bypassing of access control policies.
