Summary
SSA-914168: Multiple Vulnerabilities in SIMATIC WinCC Affecting Other SIMATIC Software Products

Notes

Summary
Multiple vulnerabilities were found in SIMATIC WinCC that ultimately could allow attackers to retrieve and brute force password hashes and access other systems. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens is preparing further updates and 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
