Summary
SSA-634640: Weak Authentication Vulnerability in Siemens Industrial Edge Devices

Notes

Summary
Siemens Industrial Edge Devices contain a weak authentication vulnerability that could facilitate an unauthenticated remote attacker to circumvent authentication and impersonate a legitimate user. Siemens has released new versions 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
