How to fix
Block network access to the embedded HTTP server from untrusted clients, or migrate to Tomcat-based TomEE distributions.
Technical details
The embedded OpenEJB HTTP server dispatches certain requests to Basic-authenticated REST endpoints without validating credentials. Remote unauthenticated attackers can invoke protected resources by exploiting this authentication bypass. The vulnerability requires the embedded HTTP server to be deployed with Basic authentication configured; Tomcat-based TomEE distributions are unaffected.
