1. Summary:

Fuse ESB Enterprise 7.1.0 Patch 3, which fixes three security issues and
various bugs, is now available from the Red Hat Customer Portal.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

2. Description:

Fuse ESB Enterprise, based on Apache ServiceMix, provides an integration

This release of Fuse ESB Enterprise 7.1.0 Patch 3 is an update to Fuse ESB
Enterprise 7.1.0 and includes bug fixes. Refer to the readme file included
with the patch files for information about the bug fixes.

The following security issues are also fixed with this release:

If web services were deployed using Apache CXF with the WSS4JInInterceptor
enabled to apply WS-Security processing, HTTP GET requests to these
services were always granted access, without applying authentication
checks. The URIMappingInterceptor is a legacy mechanism for allowing
REST-like access (via GET requests) to simple SOAP services. A remote
attacker could use this flaw to access the REST-like interface of a simple
SOAP service using GET requests that bypass the security constraints
applied by WSS4JInInterceptor. This flaw was only exploitable if
WSS4JInInterceptor was used to apply WS-Security processing. Services that
use WS-SecurityPolicy to apply security were not affected. (CVE-2012-5633)

It was found that the Apache CXF UsernameTokenPolicyValidator and
UsernameTokenInterceptor allowed a UsernameToken element with no password
child element to bypass authentication. A remote attacker could use this
flaw to circumvent access controls applied to web services by omitting the
password in a UsernameToken. This flaw was exploitable on web services that
rely on WS-SecurityPolicy plain text UsernameTokens to authenticate users.
It was not exploitable when using hashed passwords or WS-Security without
WS-SecurityPolicy. (CVE-2013-0239)

A flaw was found in the way the Spring Security Framework
DaoAuthenticationProvider performed user authentication. A remote attacker
could possibly use this flaw to determine if a username was valid or not by
observing the time differences during attempted authentication. A caller to
an Apache Camel route could possibly use this flaw to perform a
side-channel timing attacking to find valid usernames (but not their
passwords). (CVE-2012-5055)

All users of Fuse ESB Enterprise 7.1.0 as provided from the Red Hat
Customer Portal are advised to upgrade to Fuse ESB Enterprise 7.1.0 Patch
