JBoss Enterprise Portal Platform is the open source implementation of the
Java EE suite of services and Portal services running atop JBoss Enterprise
Application Platform. It comprises a set of offerings for enterprise
customers who are looking for pre-configured profiles of JBoss Enterprise
Middleware components that have been tested and certified together to

This release of JBoss Enterprise Portal Platform 5.2.1 serves as a
replacement for JBoss Enterprise Portal Platform 5.2.0, and includes bug
fixes. Refer to the JBoss Enterprise Portal Platform 5.2.1 Release Notes
for information on the most significant of these changes. The Release Notes
will be available shortly from

The following security issues are also fixed with this release:

It was found that RESTEasy was vulnerable to XML External Entity (XXE)
attacks. If a remote attacker submitted a request containing an external
XML entity to a RESTEasy endpoint, the entity would be resolved, allowing
the attacker to read files accessible to the user running the application
server. This flaw affected DOM (Document Object Model) Document and JAXB
(Java Architecture for XML Binding) input. (CVE-2012-0818)

It was found that the Attribute Exchange (AX) extension of OpenID4Java was
not checking to ensure attributes were signed. If AX was being used to
receive information that an application only trusts the identity provider
to assert, a remote attacker could use this flaw to conduct
man-in-the-middle attacks and compromise the integrity of the information
via a specially-crafted request. By default, only the JBoss Seam openid
example application uses OpenID4Java. (CVE-2011-4314)

JBoss Enterprise Portal Platform, along with all customized configuration

All users of JBoss Enterprise Portal Platform 5.2.0 as provided from the
