are tricked into accessing a malicious link. This can be used by an
attacker to trigger a malicious request on the affected device.

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

Siemens recommends upgrading all X-300 switch family devices to v4.1.4 or later.

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

- Restrict access to the affected systems, especially to Ports 22/TCP, 161/UDP, and 443/TCP and use trusted IP addresses
only.
- Disable SNMP service, if possible.
- Deactivate the webserver if not required, and if deactivation is supported by the product.

As a general security measure, Siemens strongly recommends protecting network access to devices with appropriate
mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends users configure the
environment according to the Siemens operational guidelines for industrial security and follow the recommendations in
the product manuals.
