Severity Level: 
Critical
Issue Date:

Affected Products: 
HP Helion Eucalyptus 3.0.2, 3.1.0 and earlier

Overview

A security vulnerability has been identified in the implementation of the SOAP interface exposed by front-end components in HP Helion Eucalyptus 3.1.0 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

HP Helion Eucalyptus front-end components (Cloud Controller and Walrus) can be accessed using the SOAP web services messaging protocol. A flaw was found in an implementation that binds external SOAP messages to internal representation, that allowed a user with valid HP Helion Eucalyptus credentials to submit messages in the internal format via external services. An external user could use this flaw to escalate privileges by injecting an effective user id, respected on some code paths, into internal messages. As a result, a malicious user with valid HP Helion Eucalyptus credentials could perform certain operations with privileges of HP Helion Eucalyptus admin user and, in some cases, gain root privileges on the HP Helion Eucalyptus host.

Solution

This issue is resolved in HP Helion Eucalyptus version 3.1.1.
