Improper Access Control in JBoss mod_cluster
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.
