## Technical details

The CSIv2 security interceptor in WildFly accepts ITTPrincipalName identity assertions in the service context without verifying transport-level authentication on IIOP EJB invocations. An unauthenticated attacker with network access to port 3528 can craft malicious IIOP requests to impersonate any principal and invoke @Remote EJBs. A fix is available from Red Hat.
