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.
A Remote Escalation of Privilege vulnerability in HPE Helion Eucalyptus version 3.3.0 through 4.3.1 was found.
HPE Helion Eucalyptus v4.3.0 and earlier does not correctly check IAM user's permissions for accessing versioned objects and ACLs. In some cases, authenticated users with S3 permissions could also access versioned data.
