Detection Guidance

Detection of this vulnerability involves identifying affected firmware versions and monitoring for signs of exploitation such as unauthorized command execution or unusual device behavior.

Specifically, check if your Acer Connect M6E 5G Portable WiFi Router is running firmware version M6E_AI_1.00.000019 or earlier, as these versions are vulnerable.

While no explicit commands are provided, you can perform the following general checks:

• Query the device firmware version via its management interface or command line.
• Monitor network traffic for suspicious MQTT broker activity or unauthorized access attempts.
• Check logs for unexpected root-level command executions or configuration changes.
• Restrict and inspect IPv6 traffic to detect potential exploitation attempts.
