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. The precondition for this scenario is a direct layer 2 access to the affected products. PROFIBUS interfaces are not affected. Siemens has released updates …

The latest product release of the SIMATIC S7-1200 CPU fixes several vulnerabilities. The most severe of these vulnerabilities could allow an attacker to take over an authenticated web session if the session token can be predicted. The attacker must have network access to the device to exploit this vulnerability. Further …

Several industrial products are affected by a vulnerability that could allow remote attackers to conduct a Denial-of-Service (DoS) attack by sending specially crafted packets to port 161/udp (SNMP). Siemens has released updates for several affected products, and recommends that customers update to the new version. Siemens is preparing further updates …

Versions of SIMATIC S7-1500, SIMATIC S7-1500 Software Controller and SIMATIC ET200SP Open Controller are affected by a denial-of-service vulnerability. An attacker with network access to the PLC can cause a Denial-of-Service condition on the network stack.

The new firmware update for the SIMATIC S7-1500 CPU firmware fixes several vulnerabilities, which may have been exploitable via network by Web application attacks or Denial-of-Service attacks with specially crafted network packets on different ports. Siemens addresses and fixes all of these issues by the new firmware update.

There are multiple vulnerabilities in the Intel Management Engine used in multiple SIMATIC IPC devices that may allow arbitrary code execution, a partial denial of service or information disclosure. For additional information see: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00141.html. Siemens provides updates for the affected devices.

A vulnerability has been identified in the integrated web server of SCALANCE X300, SCALANCE X408, and SCALANCE X414. The vulnerability could allow an attacker with network access to the device to cause a Denial-of-Service condition. The vulnerability can be triggered with publicly available tools, including vulnerability scanners. Siemens provides updates …
