Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869.

--- Comment #4 from Jason Shepherd jshepherd@redhat.com --- Statement:
OpenShift Container Platform ships a vulnerable netty library as part of the logging-elasticsearch5 container. ElasticSearch's security team has stated that the previous vulnerability, CVE-2019-16869, does not poses a substantial practical threat to ElasticSearch 6 [1]. We agree that this issue would be difficult to exploit both these vulnerabilities on OpenShift Container Platform, so we're reducing the impact of this issue to moderate and may fix it in the future release.

Red Hat Satellite ships vulnerable netty version embedded in Candlepin, however, is not directly vulnerable since HTTP requests are handled by Tomcat and not netty.

--- Comment #49 from Jonathan Christison jochrist@redhat.com --- Marking Red Hat Jboss Fuse 6 as having a moderate impact, Fuse 6 distributes affected versions of Netty, however its use in Fuse 6 fabric-gateway is not susceptible to the vulnerability as the fabric-gateway will create a new http client upon each gateway invocation, this means there is no multiplexing of connections, this is a prerequisite of HTTP smuggling/desynchronisation attacks.
This vulnerability is out of security support scope for the following products: * Red Hat JBoss Fuse 6
