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). …

Products that include the Siemens PROFINET-IO (PNIO) stack in versions prior V06.00 are potentially affected by a denial-of-service vulnerability when multiple legitimate diagnostic package requests are sent to the DCE-RPC interface. Siemens has released updates for several affected products, and recommends that customers update to the new version. Siemens is …

Two vulnerabilities have been identified in the SIMATIC S7-1200 and S7-1500 CPU families. One vulnerability could allow an attacker with network access to affected devices to modify the user program stored on these devices such that the source code differs from the actual running code. The other vulnerability could allow …

A vulnerability has been identified in several SIMATIC products. The vulnerability could allow an attacker in a Man-in-the-Middle position to modify network traffic exchanged on port 102/tcp to PLCs of the SIMATIC S7-1200, SIMATIC S7-1500 and SIMATIC SoftwareController CPU families. Siemens has released updates for several affected products, and recommends …

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 updates for several affected products, and recommends that customers update to the new version. Siemens is preparing further updates and recommends specific …
