The XPort EDGE is a next-generation wired Ethernet gateway for providing secure Ethernet connectivity to serial devices.

When configuring secure credentials for the Lantronix XPort EDGE, TLS private keys and AES encryption and decryption keys are transmitted in cleartext over the network. An attacker can sniff the network communications during configuration and capture these keys. The attacker would then have the ability to man in the middle encrypted communications using these keys.
