Red Hat Security Advisory 2012-0040-01 - Part of the Native components for JBoss Enterprise Web Platform is mod_cluster, an Apache HTTP Server based load balancer. Like mod_jk, it uses a communication channel to forward requests from httpd to an application server node. It was found that mod_cluster allowed worker nodes to register on any virtual host, regardless of the security constraints applied to other vhosts. In a typical environment, there will be one vhost configured internally for worker nodes, and another configured externally for serving content. A remote attacker could use this flaw to register an attacker-controlled worker node via an external vhost that is not configured to apply security constraints, then use that worker node to serve malicious content, intercept credentials, and hijack user sessions.
