Eucalyptus 3.0.0 through 4.0.1, when the log level is set to DEBUG or lower, logs user and system passwords, which allows local users to obtain sensitive information by reading the cloud log files.

The web services APIs in Eucalyptus 2.0 through 3.4.1 allow remote attackers to cause a denial of service via vectors related to the "network connection clean up code" and (1) Cloud Controller (CLC), (2) Walrus, (3) Storage Controller (SC), and (4) VMware Broker (VB).

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.

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.

Walrus in Eucalyptus before 3.2.2 allows remote attackers to cause a denial of service (memory, thread, and CPU consumption) via a crafted XML message containing a DTD, as demonstrated by a bucket-logging request.

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.

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 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.
