CVE-2011-4605

El (1) servicio JNDI, (2) servicio HA-JNDI, y (3) servlet HAJNDIFactory en JBoss Enterprise Application Platform v4.3.0 CP10 y v5.1.2, Web Platform v5.1.2, SOA Platform v4.2.0.CP05 y v4.3.0.CP05, Portal Platform 4.3 CP07 y v5.2.x anterior a v5.2.2, y BRMS Platform anterior v5.3.0 no restringe correctamente el acceso de escritura, permitiendo a atacantes remotos añadir, borrar o modificar elementos en un árbol JNDI mediante vectores desconocidos.

JBoss Application Server is the base package for JBoss Enterprise Application Platform, providing the core server components. The Java Naming and Directory Interface Java API allows Java software clients to locate objects or services in an application server. 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. It was found that the JBoss JNDI service allowed unauthenticated, remote write access by default. The JNDI and HA-JNDI services, and the HAJNDIFactory invoker servlet were all affected. A remote attacker able to access the JNDI service, HA-JNDI service, or the HAJNDIFactory invoker servlet on a JBoss server could use this flaw to add, delete, and modify items in the JNDI tree. This could have various, application-specific impacts.
