Siemens SCALANCE X Switches (Update B)
Devices create a new unique key upon factory reset, except when used
with C-PLUG. When used with C-PLUG the devices use the hardcoded private RSA-key
shipped with the firmware-image. An attacker could leverage this situation to a
man-in-the-middle situation and decrypt previously captured traffic.


 Devices do not create a new unique private key after factory reset.  An attacker could leverage this situation to a man-in-the-middle situation and decrypt previously captured traffic.
