TITLE

Siemens 7KM PAC Switched Ethernet Denial of service vulnerability

Trust: 0.8

sources: IVD: 563334eb-49a9-4eab-bebe-a6952dd98e94 // CNVD: CNVD-2017-24365

DESCRIPTION

In the Siemens 7KM PAC Switched Ethernet PROFINET expansion module (All versions < V2.1.3), a Denial-of-Service condition could be induced by a specially crafted PROFINET DCP packet sent as a local Ethernet (Layer 2) broadcast. The affected component requires a manual restart via the main device to recover. 7KMPACSwitchedEthernet is a switched Ethernet device from Siemens, Germany. The 7KMPAC switched Ethernet PROFINET expansion module has a denial of service vulnerability in versions prior to 2.1.3. Attackers can exploit this issue to cause a denial-of-service condition, denying service to legitimate users
