Synopsis:          Critical: RichFaces security update
Advisory ID:       RHSA-2013:1045-01
Product:           Red Hat JBoss Middleware
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-1045.html
Issue date:        2013-07-11
CVE Names:         CVE-2013-2165 

1. Summary:

An update for the RichFaces component that fixes one security issue is now
available from the Red Hat Customer Portal for Red Hat JBoss Enterprise
Application Platform 4.3.0 CP10 and 5.2.0; Red Hat JBoss Web Platform
5.2.0; Red Hat JBoss BRMS 5.3.1; Red Hat JBoss SOA Platform 4.3.0 CP05 and
5.3.1; Red Hat JBoss Portal 4.3 CP07 and 5.2.2; and Red Hat JBoss
Operations Network 2.4.2 and 3.1.2.

The Red Hat Security Response Team has rated this update as having critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Description:

RichFaces is an open source framework that adds Ajax capability into
existing JavaServer Faces (JSF) applications.

A flaw was found in the way RichFaces ResourceBuilderImpl handled
deserialization. A remote attacker could use this flaw to trigger the
execution of the deserialization methods in any serializable class deployed
on the server. This could lead to a variety of security impacts depending
on the deserialization logic of these classes. (CVE-2013-2165)

The fix for this issue introduces a whitelist to limit classes that can be
deserialized by RichFaces.

If you require to whitelist a class that is not already listed, for
example, a custom class, you can achieve this by following one of these

Method 1: Implementing the SerializableResource interface.
In RichFaces 3, this is defined at
org.ajax4jsf.resource.SerializableResource and in RichFaces 4/5, at

Method 2: Adding the class to the resource-serialization.properties file
(a default properties file is provided once this update is applied).
To do this you can extend the framework provided properties file that is
available under org.ajax4jsf.resource in RichFaces 3 and
org.richfaces.resource in RichFaces 4/5. The modified properties file has
to be copied into the classpath of your deployment under the
version-specific packages.

Where possible, it is recommended that Method 1 be followed.

Red Hat would like to thank Takeshi Terada (Mitsui Bussan Secure
Directions, Inc.) for reporting this issue.

Network, also back up the Red Hat JBoss Operations Network server's file
system directory.

For Red Hat JBoss BRMS, Red Hat JBoss SOA Platform, and Red Hat JBoss
Portal, it is recommended to halt the server by stopping the JBoss
Application Server process before installing this update, and then after
installing the update, restart the server by starting the JBoss Application
Server process.
