The SecurityAssociation.getCredential method in JBoss Enterprise Application Platform (EAP) before 5.2.0, Web Platform (EWP) before 5.2.0, BRMS Platform before 5.3.1, and SOA Platform before 5.3.1 returns the credentials of the previous user when a security context is not provided, which allows remote attackers to gain privileges as other users.
The AuthorizationInterceptor in JBoss Enterprise Application Platform (EAP) before 5.2.0, Web Platform (EWP) before 5.2.0, BRMS Platform before 5.3.1, and SOA Platform before 5.3.1 does not properly restrict access, which allows remote authenticated users to bypass intended role restrictions and perform arbitrary JMX operations via unspecified vectors.
The GUI installer in JBoss Enterprise Application Platform (EAP) and Enterprise Web Platform (EWP) 5.2.0 and possibly 5.1.2 uses world-readable permissions for the auto-install XML file, which allows local users to obtain the administrator password and the sucker password by reading this file.
