The embedded OpenEJB HTTP server dispatches some requests to REST endpoints configured for HTTP Basic authentication without verifying credentials. A remote unauthenticated attacker can invoke protected resources, bypassing authentication. Only deployments that use the embedded HTTP server with Basic authentication are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.
