Description
Description
When Hessian remoting endpoints are served by the embedded HTTP server, configured authentication and transport security requirements are silently ignored. A remote unauthenticated attacker can invoke the exposed EJB methods without credentials or over an unencrypted connection. Only deployments that use the embedded HTTP server rather than Tomcat and rely on these settings are affected. Users are recommended to block network access to Hessian endpoints from untrusted clients, or to migrate to another remoting protocol.
