An update for JBoss Enterprise Web Platform 5.1.2 that fixes one security
issue is now available from the Red Hat Customer Portal.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

JBoss Application Server is the base package for JBoss Enterprise Web
Platform, providing the core server components. The Java Naming and
Directory Interface (JNDI) 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 (port 1099), HA-JNDI service (port 1100), 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. (CVE-2011-4605)

Red Hat would like to thank Christian Schlüter (VIADA) for reporting this
