SSA-113131: Denial of Service Vulnerabilities in SIMATIC S7-400 CPUs

Advisory ansehen veröffentlicht 2018-11-13

Two vulnerabilities have been identified in the SIMATIC S7-400 CPU family that could allow an attacker to cause a denial of service condition. In order to exploit the vulnerabilities, an attacker must have access to the affected devices on port 102/tcp via Ethernet, PROFIBUS or Multi Point Interfaces (MPI). 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.
