HP Helion Eucalyptus Security Advisory
Advisory ID: 
Severity Level: 
Issue Date: 
Last Updated: 
Affected Products: 
HP Helion Eucalyptus 2.0.3, 3.0.1 and earlier


A security vulnerability has been identified in HP Helion Eucalyptus 3.0.1 and earlier. An update is now available that resolves this issue. We advise immediately updating all affected HP Helion Eucalyptus installations following the instructions below.


Walrus is a storage service included with HP Helion Eucalyptus. It allows users to store and access persistent data organized as buckets and objects. A flaw was found in the way Walrus performs authentication of users. An attacker could submit a specially-crafted REST request to the Walrus public interface that would allow the attacker to authenticate as an HP Helion Eucalyptus admin user and potentially gain full access to objects stored on Walrus.


HP Helion Eucalyptus versions 3.0.2 and 3.1.0 resolve this issue.
