BayTech RPC-3 Telnet Daemon Remote Authentication Bypass

This script is Copyright (C) 2005-2011 Tenable Network Security, Inc.


Synopsis :

The remote TELNET server is affected by an authentication bypass flaw.

Description :

The remote host is running a version of Bay Technical Associates RPC3
TELNET Daemon that lets a user bypass authentication by sending a
special set of keystrokes at the username prompt. Since BayTech RPC3
devices provide remote power management, this vulnerability enables an
attacker to cause a denial of service, shut down the device itself as
well as any connected devices.
