CVE-2022-2081

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.

Summary		(es) Existe una vulnerabilidad en la función HCI Modbus TCP incluida en las versiones de producto enumeradas anteriormente. Si HCI Modbus TCP está habilitado y configurado, un atacante podría aprovechar la vulnerabilidad enviando un mensaje especialmente manipulado a la RTU500 a alta velocidad, lo que provocaría que la CMU RTU500 objetivo se reiniciara. La vulnerabilidad se debe a una falta de control de inundaciones que eventualmente, si se explota, provoca un desbordamiento de pila interna en la función HCI Modbus TCP.
