=====================================================================

1. Summary:

This advisory contains instructions on how to resolve one security issue
found in the JBoss Remoting component, which is included in Red Hat JBoss
Enterprise Application Platform 5.2.0, Red Hat JBoss BRMS 5.3.1, Red Hat
JBoss Portal Platform 5.2.2, and Red Hat JBoss SOA Platform 5.3.1.

The Red Hat Security Response Team has rated this security issue 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.

2. Description:

JBoss Remoting is a stand-alone project that provides an API for making
remote invocations using pluggable transports and data marshallers.

JBoss Application Server 5 and supported Red Hat JBoss 5.x products contain
JBoss Remoting, which includes a partial implementation of the JMX remoting
specification JSR 160. This implementation is provided in jmx-remoting.sar,
which is deployed by default in unsupported community releases of JBoss
Application Server 5.x. This implementation does not implement security as
defined in JSR 160, and therefore does not apply any authentication or
authorization constraints. A remote attacker could use this flaw to
potentially execute arbitrary code on a vulnerable server. All of the
supported Red Hat JBoss 5.x products are not affected by this issue in
their default configuration. These products are only vulnerable if JMX
remoting is enabled by manually deploying jmx-remoting.sar from the
jboss-as/docs/examples directory. Unsupported community releases of JBoss
Application Server 5.x are affected. All users of the standalone JBoss
Remoting project are also affected. (CVE-2014-3518)

Red Hat would like to thank Harun ESUR of Sceptive for reporting this
issue.

All users of Red Hat JBoss Enterprise Application Platform 5.2.0, Red Hat
JBoss BRMS 5.3.1, Red Hat JBoss Portal Platform 5.2.2, and Red Hat JBoss
SOA Platform 5.3.1 as provided from the Red Hat Customer Portal who have
jmx-remoting.sar deployed are advised to follow the instructions provided
in the Solution section of this advisory.

3. Solution:

In case your server is affected, undeploy jmx-remoting.sar if JMX remoting
is not required by your applications. If your applications do require it,
secure JMX remoting by following the instructions at
