CVE-2019-5107
A cleartext transmission vulnerability exists in the network communication functionality of WAGO e!Cockpit version 1.5.1.1. An attacker with access to network traffic can easily intercept, interpret, and manipulate data coming from, or destined for e!Cockpit. This includes passwords, configurations, and binaries being transferred to endpoints.

* Follow the instructions in WAGO's handbook Cyber Security for Controller * Restrict network access to the device. * Do not directly connect the device to the internet * Use an encrypted VPN connection to the device * Disable unused TCP/UDP-ports Typically the e!Cockpit communication is only needed during commissioning of the programmable logic controller and not during normal operations. WAGO highly recommends disabling the TCP Port 11740 and UDP Port 1740 after commissioning or using an encrypted VPN connection to the device.
