Summary
SSA-783481: Denial-of-Service Vulnerability in LOGO! 8 BM

Notes

Summary
A Denial-of-Service vulnerability has been identified in LOGO! 8 BM. This vulnerability could allow an attacker to crash a device, if a user is tricked into loading a malicious project file onto an affected device. The vulnerability is related to the hardware of the product. Siemens has released new hardware versions with the LOGO! V8.4 BM product family for several affected devices in which this vulnerability is fixed. Siemens is working on new hardware versions for the SIPLUS devices to address this issue further. See the chapter "Additional Information" below for more details. For more information please also refer to the related product support article: https://support.industry.siemens.com/cs/ww/en/view/109826554/.
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.
