Eucalyptus before 3.1.1 does not properly restrict the binding of external SOAP web-services messages, which allows remote authenticated users to bypass unspecified authorization checks and obtain direct access to a (1) Cloud Controller or (2) Walrus service via a crafted message, as demonstrated by changes to a volume, snapshot, or cloud configuration setting.
The VMware Broker in Eucalyptus 2.0.3 and 3.0.x before 3.0.2 does not properly authenticate SOAP requests, which allows remote attackers to execute arbitrary VMware Broker API commands.
