Red Hat Security Advisory: jbossas security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1023 Final 1 1 2012-06-20T15:56:00Z Current version 2012-06-20T15:56:00Z 2012-06-20T15:56:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-06-20T16:08:35Z 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 issue. Warning: Before applying this update, back up your JBoss Enterprise Web Platform's "jboss-as-web/server/[PROFILE]/deploy/" directory and any other customized configuration files. All users of JBoss Enterprise Web Platform 5.1.2 as provided from the Red Hat Customer Portal are advised to install this update.
