PHOENIX CONTACT: Niche Ethernet Stack for ILC1x0, ILC1x1 and AXC 1050 Industrial controllers and CHARX control DC
Third party Niche Ethernet stack has several vulnerabilities announced by the security researcher's community. Phoenix Contact Classic Line industrial controllers are developed and designed for the use in closed industrial networks. The communication protocols and device access do not feature authentication measures. Remote attackers can use specially crafted IP packets to cause a Denial of Service or a Breach of Integrity of the PLC.

Phoenix Contact Classic Line Controllers are designed and developed for the use in closed industrial networks. The control and configuration protocols do not feature authentication mechanisms by design. Phoenix Contact therefore strongly recommends using the devices exclusively in closed networks and protected by a suitable firewall. Phoenix Contact is offering the mGuard product family for network segmentation and protection.
