The embedded OpenEJB HTTP server does not restrict static resource paths to the configured resource directories. A remote unauthenticated attacker can read arbitrary files accessible to the server process. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.
