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.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
