Security researchers published information on vulnerabilities known as ZombieLoad and Microarchitectural Data Sampling (MDS). These vulnerabilities affect many modern processors from different vendors to a varying degree. Several Siemens Industrial Products contain processors that are affected by the vulnerabilities.

Two vulnerabilities have been identified in SIMATIC S7-300 and S7-400 CPU families. One vulnerability could lead to a Denial-of-Service, the other vulnerability could result in credential disclosure. Siemens recommends specific mitigations. Siemens will update this advisory when new information becomes available.

SiNVR V3 contains several vulnerabilities in the components Central Control Server (CCS), as well as in the FTP and streaming services of the Video Server. The vulnerabilities involve path traversal (CVE-2019-19290, CVE-2019-19296, CVE-2019-19297), information disclosure (CVE-2019-19291, CVE-2019-19299), SQL injection (CVE-2019-19292), cross-site scripting (CVE-2019-19293, CVE-2019-19294), insufficient logging (CVE-2019-19295), and denial-of-service (CVE-2019-19298). …

The latest firmware update for the S7-300 CPUs fixes a vulnerability that could allow an unauthenticated attacker with network access to cause a denial-of-service condition. SINUMERIK 840D sl Controller, which contains a S7-300 CPU, is also affected. Siemens is preparing further updates and recommends specific countermeasures until patches are available.

A Cross-Site Scripting (XSS) vulnerability was found in the Engineering User Interface of Spectrum Power™ 5. A software update is available to address the issue and Siemens recommends installing the patch.

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 …

Intel has published information on vulnerabilities in Intel products in November 2019. In this advisory Siemens only explicitly mentions the vulnerabilities from the "Intel® CPU Security Advisory" and one vulnerability from "Intel® CSME, Intel® SPS, Intel® TXE, Intel® AMT, Intel® PTT and Intel® DAL Advisory" and lists the Siemens IPC …
