Synopsis:          Important: apache-cxf security update
Advisory ID:       RHSA-2013:0645-01
Product:           JBoss Enterprise Application Platform
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-0645.html

CVE Names:         CVE-2012-5633 CVE-2013-0239 
=====================================================================

1. Summary:

An update for the Apache CXF component of JBoss Enterprise Application
Platform 6.0.1 which fixes two security issues 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:

Apache CXF is an open source services framework.

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)

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)

Warning: Before applying this update, back up your existing JBoss
Enterprise Application Platform installation and deployed applications.

All users of JBoss Enterprise Application Platform 6.0.1 as provided from
the Red Hat Customer Portal are advised to apply this update.

The References section of this erratum contains a download link (you must
