Descriptions

Hammer CLI, a CLI utility for Foreman, before version 0.10.0, 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.

Hammer CLI, una utilidad CLI para Foreman, en versiones anteriores a la 0.10.0, no estableció explícitamente la marca verify_ssl para apipie-bindings que lo deshabilita por defecto. Como resultado, los certificados del servidor no se comprueban y las conexiones son propensas a ataques Man-in-the-Middle (MitM).

It was found that the hammer_cli command line client disables SSL/TLS certificate verification by default. A man-in-the-middle (MITM) attacker could use this flaw to spoof a valid certificate.
