For example, discrepancies can arise in\n\t   how to handle duplicate headers like two Transfer-encoding\n\t   (TE) or two Content-length (CL), or the malicious HTTP\n\t   message will have different headers for TE and\n\t   CL.\nThe inconsistent parsing and interpretation of messages\n\t   can allow the adversary to \"smuggle\" a message to the\n\t   client\u002Fserver without the intermediary being aware of it.\nThis weakness is usually the result of the usage\n\t   of outdated or incompatible HTTP protocol versions in the\n\t   HTTP agents.","Incomplete","Base","Simple",1,false,[],{"title":129,"metaDescription":130,"keywords":131,"canonicalUrl":132,"structuredData":133},"What is CVE-2017-2666?
