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.

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.

Apache CloudStack 4.1 to 4.8.1.0 and 4.9.0.0 contain an API call designed to allow a user to register for the developer API. If a malicious user is able to determine the ID of another (non-"root") CloudStack user, the malicious user may be able to reset the API keys for the other user, in turn accessing their account and resources.

Multiple cross-site scripting (XSS) vulnerabilities in Apache CloudStack before 4.1.1 allow remote attackers to inject arbitrary web script or HTML via the (1) Physical network name to the Zone wizard; (2) New network name, (3) instance name, or (4) group to the Instance wizard; (5) unspecified "multi-edit fields;" and (6) unspecified "list view" edit fields related to global settings.
