How to fix?

Overview

org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine.

Affected versions of this package are vulnerable to Web Cache Poisoning. An HTTP/1 style request line (i.e. method space URI space version) that declares a version of HTTP/0.9 was accepted and treated as a 0.9 request. If deployed behind an intermediary that also accepted and passed through the 0.9 version, the response sent could be interpreted by the intermediary as HTTP/1 headers. This could be used to poison the cache if the server allowed the origin client to generate arbitrary content in the response.
