Descriptions
HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header.
"El archivo HttpObjectDecoder.java en Netty versiones anteriores a 4.1.44, permite que un encabezado Content-Length esté acompañado por un segundo encabezado Content-Length o por un encabezado Transfer-Encoding."
A flaw was found in Netty before version 4.1.44, where it accepted multiple Content-Length headers and also accepted both Transfer-Encoding, as well as Content-Length headers where it should reject the message under such circumstances. In circumstances where Netty is used in the context of a server, it could result in a viable HTTP smuggling vulnerability.
