Endpoint Vulnerability

Origin Leak:ntpqandntpdcDisclose Origin Timestamp to Unauthenticated Clients

Description

To prevent off-path attackers from impersonating legitimate peers, clients require that the origin timestamp in a received response packet match the transmit timestamp from its last request to a given peer. Under assumption that only the recipient of the request packet will know the value of the transmit timestamp, this prevents an attacker from forging replies.
