Red Hat Security Advisory 2012-1013-01


Red Hat Security Advisory 2012-1013-01 - The Java Authorization Contract for Containers specification defines Permission classes and the binding of container access decisions to operations on instances of these permission classes. JaccAuthorizationRealm performs authorization based on Java ACC permissions and a Policy implementation. When a JBoss server is configured to use JaccAuthorizationRealm, the WebPermissionMapping class creates permissions that are not checked and can permit access to users without checking their roles. If the ignoreBaseDecision property is set to true on JBossWebRealm, the web authorization process is handled exclusively by JBossAuthorizationEngine, without any input from JBoss Web. This allows any valid user to access an application, without needing to be assigned the role specified in the application's web.xml "security-constraint" tag.
