"The web server of affected devices does not properly validate input
that is used for a user redirection. This could allow an attacker to
make the server redirect the legitimate user to an attacker-chosen
URL. For a successful exploit, the legitimate user must actively click
on an attacker-crafted link.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.

Siemens has released new versions for several affected products and recommends users update to the latest versions.
Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes are not, or
not yet available:

- SIMATIC Drive Controller CPU: Update to V3.1.4 or later version

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

- All affected products: Do not click on links from unknown sources.

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.

Additional information on industrial security by Siemens can be found on the Siemens industrial security webpage
