Summary
SSA-789208: Multiple Vulnerabilities (INFRA:HALT) in Interniche IP-Stack based Low Voltage Devices

Notes

Summary
Security researchers discovered and disclosed 14 vulnerabilities in the Interniche IP stack, also known as "INFRA:HALT" vulnerabilities [0]. This advisory describes the impact to Siemens low voltage products, which are only affected by four out of the 14 vulnerabilities. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens 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
