Apache CloudStack 4.5.x before 4.5.2.1, 4.6.x before 4.6.2.1, 4.7.x before 4.7.1.1, and 4.8.x before 4.8.0.1, when SAML-based authentication is enabled and used, allow remote attackers to bypass authentication and access the user interface via vectors related to the SAML plugin.
Apache CloudStack before 4.5.2 does not properly preserve VNC passwords when migrating KVM virtual machines, which allows remote attackers to gain access by connecting to the VNC server.
Apache CloudStack before 4.5.2 might allow remote authenticated administrators to obtain sensitive password information for root accounts of virtual machines via unspecified vectors related to API calls.
