Summary
SSA-868571: Missing Server Certificate Validation in IAM Client

Notes

Summary
Multiple Siemens products are affected by improper certificate validation in IAM Client. This could allow an unauthenticated remote attacker to perform man in the middle attacks. Siemens is preparing fix versions and recommends 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. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
