Summary
SSA-280603: Denial of Service Vulnerability in SINUMERIK ONE and SINUMERIK MC

Notes

Summary
A vulnerability has been identified in the integrated S7-1500 CPU of SINUMERIK ONE and SINUMERIK MC products that could allow an attacker to cause a denial of service condition. In order to exploit the vulnerability, an attacker must have access to the affected devices on port 102/tcp. Siemens is preparing updates and recommends specific countermeasures for products where updates are not, or not yet available. Note: The affected integrated S7-1500 CPUs and related products are advised in [1]. [1] https://cert-portal.siemens.com/productcert/html/ssa-592380.html
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.
