Apache CloudStack contains an authentication module providing "single sign-on" functionality via the SAML data format. Under certain conditions, a user could manage to access the user interface without providing proper credentials. As the SAML plugin is disabled by default, this issue only affects installations that have enabled and use SAML-based authentication.
