| Doc Text: |
A flaw was found in the `inets` httpd server, part of Erlang/OTP. The server incorrectly processes HTTP requests that contain both `Transfer-Encoding: chunked` and `Content-Length` headers, failing to reject them or close the connection as required by RFC 9112 §6.1. When `inets` is deployed behind a reverse proxy that prioritizes the `Content-Length` header, a remote attacker can exploit this discrepancy to smuggle malicious requests. This can lead to bypassing access controls, poisoning responses for other users, and circumventing authentication mechanisms enforced by the proxy.
