Summary

Attacker can drop certain headers in net/http/httputil

Details

ReverseProxy can be made to forward certain hop-by-hop headers, including Connection. If the target of the ReverseProxy is itself a reverse proxy, this lets an attacker drop arbitrary headers, including those set by the ReverseProxy.Director.
