Summary
SSA-871035: Session-Memory Deserialization Vulnerability in Siemens Engineering Platforms Before V19
Notes
Summary
Affected products do not properly sanitize user-controllable input when parsing files. This could allow an attacker to cause a type confusion and execute arbitrary code within the affected application.
Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further 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
