Last modified Jun 17, 2026

CVE-2017-2681 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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. EPSS estimates a 0.91% chance of exploitation in the next 30 days.

Description

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.
