Summary
SSA-594438: Remote Code Execution and Denial-of-Service Vulnerability in multiple RUGGEDCOM ROX products

Notes

Summary
A vulnerability in the RUGGEDCOM ROX devices' third party component, NSS, could allow an attacker to remotely execute code or cause a denial-of-service condition due to the way it verifies security certificates. Siemens has released updates for the affected products and recommends to update to the latest versions.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
