Severity Level: 
Important
Issue Date:

Last Updated:

Affected Products: 
HP Helion Eucalyptus 3.2.0 and earlier

Overview

A security vulnerability has been identified in the internal message protocol used by HP Helion Eucalyptus components to communicate with Walrus in HP Helion Eucalyptus 3.2.0 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.

Description

Walrus is a storage service included with HP Helion Eucalyptus. It supports an internal REST API that is used by HP Helion Eucalyptus components to access data stored on Walrus. The internal message protocol did not require all supported request headers to be signed. This flaw allowed intercepted internal requests to Walrus to be modified to manipulate (in a limited way) data stored on Walrus. Modified requests could be used to perform tasks including deleting or uploading snapshots.

Solution

HP Helion Eucalyptus version 3.2.1 resolves this issue.
