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 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.
