Summary
IEC 60870-5-104 used in RTU500: Potential Denial of Service impact on reception of invalid U-format frame. Product is only affected if IEC 60870-5-104 bi-directional functionality is configured. Enabling secure communication following IEC 62351-3 does not remediate the vulnerability but mitigates the risk of exploitation.

CVE-2022-2081 (GCVE-0-2022-2081)
Vulnerability from nvd – Published: 2024-01-04 09:15 – Updated: 2025-05-22 18:20
VLAI
Summary
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.

Title
Specially Crafted Modbus TCP Packet Vulnerability in RTU500 series
Summary
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.
Severity
7.5 (High)
CWE
- CWE-1284 - Improper Validation of Specified Quantity in Input

CVE-2022-2081 (GCVE-0-2022-2081)
Vulnerability from cvelistv5 – Published: 2024-01-04 09:15 – Updated: 2025-05-22 18:20
VLAI
Summary
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.

Title
Specially Crafted Modbus TCP Packet Vulnerability in RTU500 series
Summary
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.
Severity
7.5 (High)
