Security researchers published information on vulnerabilities known as Spectre and Meltdown. These vulnerabilities affect many modern processors from different vendors to a varying degree. Several Industrial Products include affected processors and are affected by the vulnerabilities.

SIPROTEC 4 and SIPROTEC Compact devices are affected by several vulnerabilities. Two of the vulnerabilities could allow attackers to perform a denial-of-service attack under certain conditions. Siemens has released updates for several affected products, is working on updates for the remaining affected products, and recommends specific countermeasures until fixes are …

The EN100 Ethernet communication module, which is an optional extension for SIPROTEC 4, SIPROTEC Compact and Reyrolle devices, allows an unauthenticated upload of firmware updates to the communication module in affected versions. Siemens has released updates for several affected products, is working on updates for the remaining affected products, and …

SIPROTEC 4 and SIPROTEC Compact devices could allow access authorization passwords to be reconstructed or overwritten via engineering mechanisms that involve DIGSI 4 and EN100 Ethernet communication modules. Siemens has released updates for several affected products, is working on updates for the remaining affected products, and recommends specific countermeasures until …

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. 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 SIMATIC IPCs include a version of Infineon's Trusted Platform Module (TPM) firmware that mishandles RSA key generation. This makes it easier for attackers to conduct cryptographic attacks against the key material. Siemens has released updates for the affected Industrial PCs.

Intel has identified vulnerabilities in Intel Management Engine (ME), Intel Server Platform Services (SPS), and Intel Trusted Execution Engine (TXE). As several Siemens Industrial PCs use Intel technology, they are also affected. Siemens has released updates for the affected Industrial PCs.
