"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 the following update and recommends it be applied:
RUGGEDCOM ROX (products listed above): Update to v2.14.0 or later version
Siemens has identified the following specific workarounds and mitigations users can apply to reduce the risk:
- Disable IPsec unless the feature is required in the network environment. Note that IPsec is disabled by default.
As a general security measure, Siemens strongly recommends users protect 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 SiemensΓ’ΒΒ operational guidelines for Industrial Security, and follow the recommendations in the
product manuals.
Additional information on industrial security by Siemens can be found at: https://www.siemens.com/industrialsecurity.
