RHEL 5 / 6 : JBoss Web Server (RHSA-2012:1166)

Medium Nessus Plugin ID 78929


The remote Red Hat host is missing one or more security updates.


Updated mod_cluster packages that fix one security issue are now available for JBoss Enterprise Web Server 1.0.2 for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate 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.

mod_cluster is an Apache HTTP Server (httpd) based load balancer that forwards requests from httpd to application server nodes. It can use the AJP, HTTP, or HTTPS protocols for communication with application server nodes.

The RHSA-2012:0035 update for JBoss Enterprise Web Server 1.0.2 introduced a regression, causing mod_cluster to register and expose the root context of a server by default, even when 'ROOT' was in the 'excludedContexts' list in the mod_cluster configuration. If an application was deployed on the root context, a remote attacker could use this flaw to bypass intended access restrictions and gain access to that application. (CVE-2012-1154)

Warning: Before applying the update, back up your existing JBoss Enterprise Web Server installation (including all applications and configuration files).

Users of JBoss Enterprise Web Server 1.0.2 on Red Hat Enterprise Linux 5 and 6 should upgrade to these updated packages, which resolve this issue. Apache Tomcat must be restarted for this update to take effect.
