CWE-319: Cleartext Transmission of Sensitive Information


e!Cockpit is programming software provided by WAGO for working with various product lines produced by WAGO. This software is used to write IEC-61131-3 specified language that can then be compiled for a programmable logic controller to run. This software is required to be able to communicate with these devices, and it can be found in any environment that you find an industrial controller.

Network traffic does not utilize encryption for any communication. Sensitive information is transferred over the network, both locally to the GatewayService, as well as remotely to the PLC itself. This allows for an attacker locally, or anywhere between the end device and the programming software to listen to manipulate or drop any information they choose to.
