SSA-293562 (Last Update: 2020-08-11): Vulnerabilities in Industrial Products


2020-08-11 00:00:00 UTC


Several industrial devices are affected by two vulnerabilities that could allow an attacker to cause a Denial-of-Service condition via PROFINET DCP network packets under certain circumstances. The precondition for this scenario is a direct layer 2 access to the affected products. PROFIBUS interfaces are not affected.

Siemens has released updates for several affected products and recommends to update to the new versions. Siemens is preparing further updates and recommends specific countermeasures for products where updates are not, or not yet available.
