DESCRIPTION:
Multiple vulnerabilities have been reported in Rockwell Automation
ControlLogix, which can be exploited by malicious people to disclose
system information, cause a DoS (Denial of Service), and compromise a
vulnerable device.

1) An input validation error when processing certain commands can be
exploited to cause a device to stop responding.

2) An input validation error when processing certain packets can be
exploited to cause a device to stop responding.

3) An error when processing interface control commands can be
exploited to cause a device to stop responding.

4) An error when processing the stop command can be exploited to
cause a device to stop responding.

5) An error when processing the dump command can be exploited to
disclose the device's boot code, which may contain sensitive
information.

6) An error when processing the reset command can be exploited to
cause a device to stop responding.

7) An error within the upgrade functionality can be exploited to
upload malicious firmware.

SOLUTION:
Restrict access to trusted hosts only.
