Description Martin Prpič 2017-03-27 14:13:39 UTC
Tomas Strachota of Red Hat reports:

It was found that Hammer CLI, a CLI utility for Foreman, did not explicitly set the verify_ssl flag for apipie-bindings that disable it by default. As a result the server certificates are not checked and connections are prone to man-in-the-middle attacks.
