A vulnerability exists in the HCI Modbus TCP function included in the product versions listed above. If the HCI Modbus TCP is en-abled and configured, an attacker could exploit the vulnerability by sending a specially crafted message to the RTU500, causing the receiving RTU500 CMU to reboot. The vulnerability is caused by the validation error in the length information carried in MBAP header in the HCI Modbus TCP function.
