Summary
Weidmueller: EtherNet/IP Fieldbus Coupler out-of-bounds write
Notes
Summary: A critical vulnerability has been discovered in the utilized component EtherNet/IP Adapter Development Kit (EADK) by Pyramid Solutions, Inc.. For details refer to CVE(s).This vulnerability may allow an attacker to send a specially crafted packet that may result in a denial-of-service condition of the affected products. The indicated firmware versions are only used on products of hardware version 01.xx.xx.
Impact: Attackers with network access to the EtherNet/IP network may send a specially crafted packet that may result in a denial-of-service condition of the affected products which will cause them to crash. Crashed products will reboot within some seconds.
Mitigation: Weidmueller strongly recommends applying the following external protective measures: Restrict network access to the EtherNet/IP network containing affected products. If remote access is required, use secure methods such as virtual private networks (VPNs).
