Siemens has identified the following specific workarounds and mitigations users can apply to reduce risk:

(CVE-2023-52237, CVE-2023-52238) Disable the webserver if not required on the affected systems. Restrict the access to Port 80/tcp and 443/tcp to trusted IP address only

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms.
To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens' operational guidelines for industrial security and following recommendations in the product manuals.
