Summary
SSA-618620: Vulnerabilities in Boot Loader (U-Boot) of RUGGEDCOM ROS Devices

Notes

Summary
The boot loader within RUGGEDCOM ROS contains two vulnerabilities in the loading process of the operating system kernel. The more severe of these vulnerabilities could allow an attacker with local access to the device to execute arbitrary code on an affected device. Siemens recommends specific countermeasures to mitigate this issue.
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
