An update for JBoss Enterprise Application Platform 5.1.2 that fixes one
security issue is now available from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having moderate

which gives a detailed severity rating, is available from the CVE link in
the References section.
The Java Authorization Contract for Containers (Java ACC) 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
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. (CVE-2012-1167)
