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.

Walrus in Eucalyptus before 3.2.2 does not verify authorization for the GetBucketLoggingStatus, SetBucketLoggingStatus, and SetBucketVersioningStatus bucket operations, which allows remote authenticated users to bypass intended restrictions on (1) modifying the logging setting, (2) modifying the versioning setting, or (3) accessing activity logs via a request.

The gather log service in Eucalyptus before 3.3.1 allows remote attackers to read log files via an unspecified request to the (1) Cluster Controller (CC) or (2) Node Controller (NC) component.

The internal message protocol for Walrus in Eucalyptus 3.2.0 and earlier does not require signatures for unspecified request headers, which allows attackers to (1) delete or (2) upload snapshots.

Eucalyptus before 3.1.1 does not properly restrict the binding of external SOAP web-services messages, which allows remote authenticated users to gain privileges by sending a message to (1) Cloud Controller or (2) Walrus with the internal message format and a modified user id.

The Apache Santuario configuration in Eucalyptus before 3.1.1 does not properly restrict applying XML Signature transforms to documents, which allows remote attackers to cause a denial of service via unspecified vectors.
