Red Hat Security Advisory 2014-0886-00
Posted Jul 15, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-0886-00 - Red Hat JBoss Enterprise Application Platform is a platform for Java applications, which integrates the JBoss Application Server with JBoss Hibernate and JBoss Seam. It was found that the implementation of the org.picketlink.common.util.DocumentUtil.getDocumentBuilderFactory() method provided a DocumentBuilderFactory that would expand entity references. A remote, unauthenticated attacker could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.
