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.
Eucalyptus before 2.0.3 and Eucalyptus EE before 2.0.2, as used in Ubuntu Enterprise Cloud (UEC) and other products, do not properly interpret signed elements in SOAP requests, which allows man-in-the-middle attackers to execute arbitrary commands by modifying a request, related to an "XML Signature Element Wrapping" or a "SOAP signature replay" issue.
The password reset feature in the administrator interface for Eucalyptus 2.0.0 and 2.0.1 does not perform authentication, which allows remote attackers to gain privileges by sending password reset requests for other users.
