Foreman versions before 2.3.4 and before 2.4.0 is affected by an improper authorization handling flaw. An authenticated attacker can impersonate the foreman-proxy if product enable the Puppet Certificate authority (CA) to sign certificate requests that have subject alternative names (SANs). Foreman do not enable SANs by default and `allow-authorization-extensions` is set to `false` unless user change `/etc/puppetlabs/puppetserver/conf.d/ca.conf` configuration explicitly.
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
