CVE-2017-2681: Siemens Dk Standard Ethernet Controller Firmware

Medium severity, CVSS 6.5. EPSS: 0.9% chance of exploitation in the next 30 days.

Specially crafted PROFINET DCP packets sent on a local Ethernet segment (Layer 2) to an affected product could cause a denial of service condition of that product. Human interaction is required to recover the system. PROFIBUS interfaces are not affected.
