A vulnerability in affected devices could allow an attacker to perform a denial-of-service attack if a large amount of Profinet Discovery and Configuration Protocol (DCP) reset packets is sent to the affected devices. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens …

A vulnerability exists in affected products that could allow remote attackers to affect the availability of the devices under certain conditions. The underlying TCP stack can be forced to make very computation expensive calls for every incoming packet which can lead to a Denial-of-Service.

Security researchers discovered and disclosed 33 vulnerabilities in several open-source TCP/IP stacks for embedded devices, also known as “AMNESIA:33” vulnerabilities. This advisory describes the impact of two of these vulnerabilities (CVE-2020-13987, CVE-2020-17437) to Siemens products. Siemens has released updates for several affected products and recommends to update to the latest …

A vulnerability has been identified in the underlying TCP/IP stack of LOGO! CMR and SIMATIC RTU 3000 devices. It could allow an attacker with network access to the LAN interface of an affected device to hijack an ongoing connection or spoof a new one. The WAN interface, however, is not …

Vulnerabilities in the third-party component strongSwan could allow an attacker to cause a denial of service (DoS) condition in affected devices by exploiting integer overflow bugs. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens is preparing further updates and recommends specific …

A vulnerability in several SCALANCE X devices could allow an unauthenticated attacker with network access to an affected device to perform a denial-of-service. Siemens has released an update for SCALANCE X-200IRT and recommends to update to the latest version. Siemens recommends specific countermeasures for products where updates are not, or …

The products listed below contain a vulnerability that could allow remote attackers to affect the availability of the devices under certain conditions. The underlying TCP stack can be forced to make very computation expensive calls for every incoming packet which can lead to a Denial-of-Service. Siemens has released an update …
