"An issue was discovered on Moxa AWK-3121 1.14 devices. The device
enables an unencrypted TELNET service by default. This allows an
attacker who has been able to gain an MITM position to easily sniff
the traffic between the device and the user. Also an attacker can
easily connect to the TELNET daemon using the default credentials if
they have not been changed by the user.

This plugin only works with Tenable.ot.
