Description

An updated jbossas package that corrects a security vulnerability is now available for Red Hat Application Stack. This update has been rated as having critical security impact by the Red Hat Security Response Team.

JBoss Application Server is a J2EE certified platform for developing and deploying enterprise Java applications, Web applications, and Portals. Symantec discovered a flaw in the DeploymentFileRepository class of the JBoss Application Server. A remote attacker who is able to access the console manager could read or write to files with the permissions of the JBoss user. This could potentially lead to arbitrary code execution as the jboss user. (CVE-2006-5750) For the Red Hat Application Stack, the jbossas service is not enabled by default. Once the jbossas service is enabled, the console manager will become accessible on port 8080. Although port 8080 will be blocked from outside access by the default Red Hat Enterprise Linux firewall rules, users should ensure that the console is not available publicly and is adequately protected by authentication as explained in the JBoss documentation. A correct configuration of the JBoss Application Server would mitigate this vulnerability to only being exploitable by users who have authorization to use the console manager. All users of Red Hat Application Stack are advised to upgrade to these updated packages, which resolve the directory traversal issue with a backported patch. These updated packages also contain a change to the default jbossas configuration file. For users installing Red Hat Application Stack for the first time, all JBoss Application Server network services, including the management consoles, will be restricted by default to localhost. No change is made for users upgrading previously installed jbossas packages. Users who already have Red Hat Application Stack installed should check to make sure that they have correctly followed the security guidelines and that the management consoles are not accessible to unauthorized users. Red Hat would like to thank Symantec for reporting this issue.
