CVE-2019-20445: Critical severity Netty Netty vulnerability

Published Jan 29, 2020
·
Updated

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.

Other sources

A vulnerability was found in 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.

— Red Hat

Netty could provide weaker than expected security, caused by non-proper handling of Content-Length and Transfer-Encoding in the HttpObjectDecoder.java. A remote attacker could exploit this vulnerability to launch further attacks on the system.
