Red Hat Security Advisory: mod_cluster security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1010 Final 1 1 2012-06-19T19:20:00Z Current version 2012-06-19T19:20:00Z 2012-06-19T19:20:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-06-19T19:26:12Z An update for JBoss Enterprise Application 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 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 JBoss Enterprise Application Platform 5.1.2 release (RHSA-2011:1805) 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 this update, back up your JBoss Enterprise Application Platform's "jboss-as/server/[PROFILE]/deploy/" directory, along with all other customized configuration files. All users of JBoss Enterprise Application Platform 5.1.2 as provided from the Red Hat Customer Portal are advised to install this update.
