Summary
SSA-969738: Denial of Service Vulnerability in SIMATIC S7-200 SMART Devices
Notes
Summary
A vulnerability in SIMATIC S7-200 SMART devices could allow an attacker to cause a denial of service condition if a specially crafted TCP packet is sent to the device.
Siemens recommends specific countermeasures for products where fixes 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.
