There is an access mode used during manufacturing of SIMATIC S7-1200 and S7-200 SMART CPUs that allows additional diagnostic functionality. Using this functionality requires physical access to the UART interface during boot process. Siemens is working on a solution and recommends specific countermeasures until the solution is available.

A vulnerability in the affected products could allow an unauthorized attacker with network access to the webserver of an affected device to perform a denial-of-service attack. Siemens has released updates for several affected products, and recommends that customers update to the new version. Siemens is preparing further updates and recommends …

The boot loader within RUGGEDCOM ROS contains two vulnerabilities in the loading process of the operating system kernel. The most severe of these vulnerabilities could allow an attacker with local access to the device to execute arbitrary code on an affected device. Siemens recommends specific countermeasures to mitigate this issue.

The latest firmware updates for the SCALANCE W700 and W1700 wireless device families fix a vulnerability affecting WPA/WPA2 key handling. It might be possible to, by manipulating the EAPOL-Key frames, decrypt the Key Data field without the frame being authenticated. This has impact on WPA/WPA2 architectures using TKIP encryption. The …

The SIPROTEC 5 Ethernet plug-in communication modules and devices are affected by multiple security vulnerabilities. These vulnerabilities could allow an attacker to leverage various attacks, e.g. to execute arbitrary code over the network. Eleven of these vulnerabilities affect the underlying Wind River VxWorks network stack and were recently patched by …

SIMATIC CP 343-1 Advanced/CP-443-1 Advanced devices and SIMATIC S7-300/S7-400 CPUs are affected by two vulnerabilities. One of the vulnerabilities could allow remote attackers to perform operations as an authenticated user under certain conditions. Siemens has released updates for SIMATIC CP 343-1 Advanced and SIMATIC CP 443-1 Advanced devices. Siemens recommends …

The latest update for Desigo PXC devices fixes a vulnerability that could allow unauthenticated remote users to cause a denial of service condition on the PX Web interface (HTTP, port tcp/80) of a device. Devices where PX Web is not enabled are not affected by this vulnerability.
