The NCCIC has published an advisory on an expected behavior violation vulnerability in Siemens SCALANCE X. Numerous products and versions of those products are affected. Successful exploitation of this vulnerability could allow an attacker to feed data over a mirror port and into the mirrored network. Siemens has identified specific workarounds/mitigations that users can implement for one of the affected products. For the others, Siemens recommends users apply defense in depth principles, particularly ensuring that no devices that transmit data back in the mirroring network are operated within the mirrored network.
