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.

Apache CloudStack 4.0.0 before 4.0.2 and Citrix CloudPlatform (formerly Citrix CloudStack) 3.0.x before 3.0.6 Patch C allows remote attackers to bypass the console proxy authentication by leveraging knowledge of the source code.

Apache CloudStack 4.0.0 before 4.0.2 and Citrix CloudPlatform (formerly Citrix CloudStack) 3.0.x before 3.0.6 Patch C uses a hash of a predictable sequence, which makes it easier for remote attackers to guess the console access URL via a brute force attack.

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.
