1.CVE-2018-10690
[Suggested description]
An issue was discovered on Moxa AWK-3121 1.14 devices.
The device by default allows HTTP traffic thus
providing an insecure communication mechanism for a user connecting to
the web server. This allows an attacker to sniff the traffic easily and
allows an attacker to compromise sensitive data such as credentials.

5. CVE-2018-10694
[Suggested description]
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.
