Show the technical text from the sources

SEPPmail Secure Email Gateway before 15.1.1 permits password recovery for a created but unregistered GINA account whose initial password is empty without adequately verifying ownership. A remote unauthenticated attacker who identifies such an account can set a new password, authenticate as that account, and prevent the intended recipient from using it until recovery.
