"An issue was discovered on Moxa AWK-3121 1.14 devices. The device
provides a Wi-Fi connection that is open and does not use any
encryption mechanism by default. An administrator who uses the open
wireless connection to set up the device can allow an attacker to
sniff the traffic passing between the user's computer and the device.
This can allow an attacker to steal the credentials passing over the
HTTP connection as well as TELNET traffic. Also an attacker can MITM
the response and infect a user's computer very easily as well.

This plugin only works with Tenable.ot.
