## Description

JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) before
6.0.1, when using role-based authorization for Enterprise Java Beans (EJB)
access, does not call the intended authorization modules, which prevents
JACC permissions from being applied and allows remote attackers to obtain
access to the EJB.
