description

Advantech ADAM-3600 EdgeLink devices are affected by an authentication weakness in the proprietary protocol. An attacker able to reach that protocol may be able to bypass its authentication controls.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Restrict access to the device's proprietary protocol to trusted administrative networks using segmentation and access controls. Monitor Advantech guidance for an update or supported remediation.
