Summary
SSA-603476: Web Vulnerabilities in SIMATIC NET CP 343-1/CP 443-1 Modules and SIMATIC S7-300/S7-400 CPUs

Notes

Summary
SIMATIC CP 343-1 Advanced/CP-443-1 Advanced devices and SIMATIC S7-300/S7-400 CPUs are affected by two vulnerabilities. One of the vulnerabilities could allow remote attackers to perform operations as an authenticated user under certain conditions. 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
