It is possible to log into the remote system using telnet without
supplying any credentials
The remote version of Kerberos telnet does not sanitize the
user-supplied 'USER' environement variable. By supplying a specially
malformed USER environment variable, an attacker may force the remote
telnet server to believe that the user has already authenticated.
