Summary
SSA-784849: Direct Memory Access Vulnerabilities in SIMATIC CP Devices

Notes

Summary
Several SIMATIC CP devices contain direct memory access vulnerabilities that could allow an attacker to execute code, access the PROFINET network without restrictions or perform denial of service attacks. Siemens recommends specific countermeasures for products where updates are not, or not yet available.
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
