Red Hat Security Advisory 2012-1109-01 - JBoss Application Server is the base package for JBoss Enterprise Portal 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. 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.
