Two vulnerabilities have been identified in the SIMATIC S7-400 CPU family 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 via Ethernet, PROFIBUS or Multi Point Interfaces (MPI). Siemens provides updates …

The latest update for SIMATIC Panel software and SIMATIC WinCC (TIA Portal) fixes a vulnerability that could allow an attacker with network access to the web server to perform a HTTP header injection attack.

IEC 61850 system configurator, DIGSI 5, DIGSI 4, SICAM PAS/PQS, SICAM PQ Analyzer, and SICAM SCC products are affected by a security vulnerability which could allow an attacker to either exfiltrate limited data from the system or to execute code with operating system user permissions. Siemens has released updates for …

The latest update for SCALANCE W1750D addresses a vulnerability known as ROBOT Attack. The vulnerability could allow an attacker to decrypt TLS traffic. Siemens provides a firmware update and recommends users to update to the new version.

Security researchers published information on vulnerabilities known as Spectre-NG (Variants 3a and 4). 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.

Several industrial controllers are affected by a security vulnerability 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 OSI Layer 2 access to the affected products. PROFIBUS interfaces are not affected. Siemens has released …

The latest updates for SIMATIC STEP 7 (TIA Portal) and SIMATIC WinCC (TIA Portal) fix two vulnerabilities. These two vulnerabilities could either allow an attacker with local file write access to manipulate files and cause a Denial-of-service-condition, or execute code both on the manipulated installation and on devices that are …
