Red Hat JBoss Portal is the open source implementation of the Java EE suite of services and Portal services running atop Red Hat JBoss Enterprise Application Platform.
It was found that PortletBridge PortletRequestDispatcher did not respect security constraints set by the servlet if a portlet request asked for rendering of a non-JSF resource such as JSP or HTML. A remote attacker could use this flaw to potentially bypass certain security constraints and gain access to restricted resources. (CVE-2015-5176)
Red Hat would like to thank Liferay, Inc. for reporting this issue.
All users of Red Hat JBoss Portal 6.2.0 as provided from the Red Hat Customer Portal are advised to apply this update.
