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.

MEDIUM5.9

A smart proxy that provides a restful API to various sub-systems of the Foreman is affected by the flaw which can cause a Man-in-the-Middle attack. The FreeIPA module of Foreman smart proxy does not check the SSL certificate, thus, an unauthenticated attacker can perform actions in FreeIPA if certain conditions are met. The highest threat from this flaw is to system confidentiality. This flaw affects Foreman versions before 2.5.0.

HIGH8.8

A flaw was found in Foreman. This vulnerability allows an authenticated remote attacker with low-level read permissions to achieve arbitrary code execution on the underlying server. By manipulating the permitted methods list within the template rendering engine, an attacker can bypass the safemode sandbox isolation and execute unauthorized commands directly on the host system.
