Description
Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority component in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution.
Statement
In OpenShift Container Platform (OCP) the affected components are behind OpenShift OAuth authentication. This restricts access to the vulnerable httpclient library to authenticated users only. Additionally the vulnerable httpclient library is not used directly in OCP components, therefore the impact by this vulnerability is Low. In OCP 4 there are no plans to maintain ose-logging-elasticsearch5 container, hence marked as wontfix.
In the Red Hat Enterprise Linux platforms, Maven 35 and 36 are affected via their respective httpcomponents-client component.
