Description

In Apache CloudStack, a gap in access control checks affected the APIs - createNetworkACL - listNetworkACLs - listResourceDetails - listVirtualMachinesUsageHistory - listVolumesUsageHistory While these APIs were accessible only to authorized users, insufficient permission validation meant that users could occasionally access information beyond their intended scope.
