Technical details
A command injection vulnerability exists in the firmware upgrade file verification process of Advantech ADAM-3600 EdgeLink. The flaw is triggered when the system processes a specially crafted firmware file, failing to properly sanitize inputs before execution. An attacker with high privileges (PR:H) can exploit this over the network to execute arbitrary system commands with the permissions of the update process. This can lead to a complete compromise of the device's integrity and availability. The vulnerability is addressed in version 2.8.5.1 and later.
