Summary

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 finds such an account can set a new password and sign in as that account, which blocks the intended recipient from using it until recovery. The weakness is classified as CWE-640.
