High impact if exploited, but EPSS currently rates exploitation as unlikely (5.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

An exploitable command injection vulnerability exists in encrypted diagnostic script functionality of the Moxa AWK-3131A firmware version 1.13. A specially crafted diagnostic script file can cause arbitrary busybox commands to be executed, resulting in remote control over the device. An attacker can send diagnostic while authenticated as a low privilege user to trigger this vulnerability.
