Descriptions

Improper parsing of HTTP requests in Pallets Werkzeug v2.1.0 and below allows attackers to perform HTTP Request Smuggling using a crafted HTTP request with multiple requests included inside the body. NOTE: the vendor's position is that this behavior can only occur in unsupported configurations involving development mode and an HTTP server from outside the Werkzeug project

** EN DISPUTA ** Un análisis inapropiado de las peticiones HTTP en Pallets Werkzeug versiones v2.1.0 y anteriores, permite a atacantes llevar a cabo un contrabando de peticiones HTTP usando una petición HTTP diseñada con múltiples peticiones incluidas en el cuerpo. NOTA: la posición del proveedor es que este comportamiento sólo puede ocurrir en configuraciones no soportadas que implican el modo de desarrollo y un servidor HTTP desde fuera del proyecto Werkzeug
