HAProxy - Load balancer

Transfer-Encoding header is not supported in HTTP/1.0. However, softwares dealing with HTTP/1.0 and HTTP/1.1 messages may accept it and transfer it. When a Content-Length header is also provided, it must be ignored. Unfortunately, this may lead to vulnerabilities (request smuggling or response splitting) if an intermediary is only implementing HTTP/1.0. Because it may ignore Transfer-Encoding header and only handle Content-Length one. To avoid any security issues, when Transfer-Encoding and Content-Length headers are found in a message, the close mode is forced. The same is performed for HTTP/1.0 message with a Transfer-Encoding header only. This change is conform to what it is described in the last HTTP/1.1 draft. See also httpwg/http-core#879. Note that Content-Length header is also removed from any incoming messages if a Transfer-Encoding header is found. However it is not true (not yet) for responses generated by HAProxy. |
