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

SIMATIC S7-400 CPUs are affected by a security vulnerability which could lead to a Denial-of-Service condition of the PLC if specially crafted packets are received and processed. The affected SIMATIC S7-400 CPU hardware versions are in the product cancellation phase or already phased-out. Siemens recommends customers either upgrading to a …

Multiple vulnerabilities have been identified in SCALANCE W1750D, SCALANCE M800, and SCALANCE S615 devices. The highest scored vulnerability could allow a remote attacker to crash the DNS service or execute arbitrary code. The attacker must be able to craft malicious DNS responses and inject them into the network in order …

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 …
