CVE-2012-1167: Medium severity jboss enterprise application platform vulnerability
The JBoss Server in JBoss Enterprise Application Platform 5.1.x before 5.1.2 and 5.2.x before 5.2.2, Web Platform before 5.1.2, BRMS Platform before 5.3.0, and SOA Platform before 5.3.0, when the server is configured to use the JaccAuthorizationRealm and the ignoreBaseDecision property is set to true on the JBossWebRealm, does not properly check the permissions created by the WebPermissionMapping class, which allows remote authenticated users to access arbitrary applications.
Other sources
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.
