"The remote OT asset is affected by a vulnerability.");
  script_set_attribute(attribute:"description", value:
"A vulnerability exists in the HCI Modbus TCP function included in the
product versions listed above. If the HCI Modbus TCP is enabled and
configured, an attacker could exploit the vulnerability by sending a
specially crafted message to the RTU500 in a high rate, causing the
targeted RTU500 CMU to reboot. The vulnerability is caused by a lack
of flood control which eventually if exploited causes an internal
stack overflow in the HCI Modbus TCP function.
