A flaw was found in the original fix for the netty-codec-http CVE-2021-21409, where the OpenShift Logging openshift-logging/elasticsearch6-rhel8 container was incomplete. The vulnerable netty-codec-http maven package was not removed from the image content. This flaw affects origin-aggregated-logging versions 3.11.
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
