Description

Red Hat has issued an update for JBoss Enterprise Application Platform and JBoss Enterprise Web Platform. This fixes a security issue, which can be exploited by malicious users to bypass certain security restrictions.

The security issue is caused due to an error in the WebPermissionMapping class when creating permissions and can be exploited to get access to an otherwise restricted application.

Successful exploitation requires that the JBoss server is configured to use JaccAuthorizationRealm and that the ignoreBaseDecision property is set to true on JBossWebRealm.

Solution
Updated packages are available via Red Hat Network.
