Siemens is preparing further updates and recommends the following mitigations until patches are available:

- Restrict network access to Port 161/UDP of the affected product.
- Disable SNMP in Versions 1 and 2c, if supported by the product.
- Enable SNMP v3 if required and supported by the product to prevent unauthorized access of the affected product.
- Enable access protection and change default credentials for SNMP service, if possible.

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 configuring the
environment according to the Siemens operational guidelines for Industrial Security, and following the recommendations
in the product manuals.
