Vulnerability Name:

CCN-5189

Published:2000-08-28
Updated:2000-08-28
Summary:Many programs that use Kerberos authentication could allow a remote attacker to spoof Key Distribution Center (KDC) responses. If the login service is not registered with the KDC, or if the service's secret key is not installed on the host, the login service bypasses verification. This could allow a remote attacker to login by spoofing KDC responses.
