mod_cluster 1.0.10 before 1.0.10 CP03 and 1.1.x before 1.1.4, as used in JBoss Enterprise Application Platform 5.1.2, when "ROOT" is set to excludedContexts, exposes the root context of the server, which allows remote attackers to bypass access restrictions and gain access to applications deployed on the root context via unspecified vectors.

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:1053 advisory.

    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 Web Platform 5.1.2 release (RHSA-2011:1804,     RHSA-2011:1803, RHSA-2011:1802) 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 Web     Platform's server/[PROFILE]/deploy/ directory and any other customized     configuration files.

    Users of JBoss Enterprise Web Platform 5.1.2 on Red Hat Enterprise Linux 4,     5, and 6 should upgrade to these updated packages, which correct this     issue. The JBoss server process must be restarted for this update to take     effect.
