ESA-08: Walrus Request Manipulation Vulnerability ==================================================================== Eucalyptus Security Advisory Advisory ID: ESA-08 Date: 2013-02-28 Severity Level: Important Affected Versions: Eucalyptus 3.2.0 and earlier CVE Number: CVE-2012-4066 ==================================================================== OVERVIEW ------------ A security vulnerability has been identified in the internal message protocol used by Eucalyptus components to communicate with Walrus in Eucalyptus 3.2.0 and earlier. An update is now available that resolves this issue. We advise immediately updating all affected Eucalyptus installations following the instructions below. DESCRIPTION ------------- Walrus is a storage service included with Eucalyptus. It supports an internal REST API that is used by 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 ------------- Eucalyptus version 3.2.1 resolves this issue. Please see http://www.eucalyptus.com/download/eucalyptus for instructions on downloading and upgrading to the latest Eucalyptus software.
