CISA's summary
Summary: A vulnerability in the affected products could allow an unauthorized attacker with network access to perform a denial-of-service attack resulting in loss of real-time synchronization. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where fixes are not, or not yet available.
