CISA's summary
Summary: A Denial-of-Service vulnerability was found in SIMATIC PCS 7, SIMATIC WinCC and SIMATIC NET PC software when encrypted communication is enabled. The vulnerability could allow an attacker with network access to cause a Denial-of-Service condition under certain circumstances (versions prior to SIMATIC WinCC V7.3 or SIMATIC PCS 7 V8.1 are not affected as encrypted communication is not an option). 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. Note: The vulnerability is part of a shared component, used by various Siemens products (SIMATIC Communication Services - SCS). The installation of a fix version of any product also removes the vulnerability for other products on the same system, even if those products were not updated.
