MS09-042: Vulnerability in Telnet Could Allow Remote Code Execution (960859)

This script is Copyright (C) 2009-2017 Tenable Network Security, Inc.

Synopsis :

Arbitrary code can be executed on the remote host through the remote
Telnet client.

Description :

The remote Telnet client does not correctly opt in to NTLM credential-
reflection protections, which ensure that a user's credentials are not
reflected back and used against the user.

If a remote attacker can trick a user on the host into connecting to a
malicious server with an affected version of the Telnet client, he can
leverage this issue to gain the rights of that user and do anything that
he has privileges to do.
