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.
