=====================================================================
1. Summary:
An update for JBoss Enterprise Portal Platform 4.3 CP07 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.
2. Description:
JBoss Application Server is the base package for JBoss Enterprise
Portal 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
issue.
Warning: Before applying this update, back up all applications deployed on
JBoss Enterprise Portal Platform, along with all customized configuration
files.
All users of JBoss Enterprise Portal Platform 4.3 CP07 as provided from the
Red Hat Customer Portal are advised to install this update.
