Severity: moderate Affected versions:
- Apache TomEE (org.apache.openejb:openejb-hessian) 4.6.0 through 4.7.5 - Apache TomEE (org.apache.tomee:openejb-hessian) 7.0.0-M1 before 10.0.0-M1 - Apache TomEE (org.apache.tomee:openejb-hessian) 10.0.0-M1 through 10.2.0 - Apache TomEE (org.apache.tomee:openejb-hessian) 11.0.0-M1 Description: When an EJB is exposed over the optional Hessian protocol inside an existing web application, some configured authentication and transport security settings are silently not enforced. A remote unauthenticated attacker can invoke the exposed EJB methods. Only deployments using the Hessian module with such settings are affected. Users are recommended to block network access to Hessian endpoints from untrusted clients, or to migrate to another remoting protocol.
