Impact of DCOM

Last Updated: July 13, 2022

In the Windows update released on June 14, 2022 (*1), the setting to enable hardening the DCOM server’s authentication level becomes the default setting. With the application of the Windows update, unintended behavior (e.g., inability to communicate etc.) has been observed in products that use DCOM technology. Yokogawa is ready to inform customers of whether or not the product operation is affected (*2), and our future policy for resolving the issue, including solutions and workarounds in the event that it is affected.

*1 This is one of a series of Windows updates that Microsoft is releasing in response to the DCOM vulnerability in Windows that was disclosed as CVE-2021-26414.

*2 The investigation results for the target products described in this document are the results of an investigation on the impact of applying the Windows update (June 14, 2022) on the DCOM server's authentication level hardening. The investigation results do not guarantee the presence or absence of effects on operations other than DCOM functions. Please refer to the information provided by our Endpoint Security Service (EPS Service) for the impact and applicability of Windows updates on each product on or after June 14, 2022.
