Foreman before 1.9.0 allows remote authenticated users with the edit_users permission to edit administrator users and change their passwords via unspecified vectors.
Foreman before 1.8.1 does not set the secure flag for the _session_id cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.
Forman before 1.7.4 does not verify SSL certificates for LDAP connections, which allows man-in-the-middle attackers to spoof LDAP servers via a crafted certificate.
