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

- Do not access the product’s web service via URLs coming from untrusted sources.
- Disable the web server if possible.
- SIMATIC PC Station (Specifically): Disable the web server. Note that this feature is disabled by default.

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate 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.
