"An issue was discovered on Moxa AWK-3121 1.14 devices. It provides
functionality so that an administrator can run scripts on the device
to troubleshoot any issues. However, the same functionality allows an
attacker to execute commands on the device. The POST parameter
iw_filename is susceptible to buffer overflow. By crafting a packet
that contains a string of 162 characters, it is possible for an
attacker to execute the attack.

This plugin only works with Tenable.ot.
