RHEL 5 / 6 : apache-cxf (RHSA-2013:0644)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated apache-cxf package for JBoss Enterprise Application
Platform 6.0.1 which fixes two security issues is now available for
Red Hat Enterprise Linux 5 and 6.

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.

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 on Red Hat
Enterprise Linux 5 and 6 are advised to upgrade to this updated
package. The JBoss server process must be restarted for the update to
take effect.
