In Apache CloudStack 4.1.0 and 4.1.1, when calling the CloudStack API call listProjectAccounts as a regular, non-administrative user, the user is able to see information for accounts other than their own.

The (1) ListNetworkACL and (2) listNetworkACLLists APIs in Apache CloudStack before 4.2.1 allow remote authenticated users to list network ACLS for other users via a crafted request.

The virtual router in Apache CloudStack before 4.2.1 does not preserve the source restrictions in firewall rules after being restarted, which allows remote attackers to bypass intended restrictions via a request.
