Overview

org.eclipse.jetty:jetty-client is an is an asynchronous http client module fro jetty server.

Affected versions of this package are vulnerable to Authorization Bypass. A large chunk size could be interpreted as a smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty was deployed behind an intermediary that imposed some authorization and that intermediary allowed arbitrarily large chunks to be passed on unchanged, then this flaw could be used to bypass the authorization imposed by the intermediary as the fake pipelined request would not be interpreted by the intermediary as a request.
