• Remote Management Interface: The vulnerability affects the remote management component, which is accessible over the network.
• Missing Authentication: The lack of authentication mechanisms allows unauthorized users to access and manipulate the device remotely.

Exploitation Methods:

• Unauthorized Access: Attackers can gain unauthorized access to the device's management interface.
• Remote Code Execution: Potential for executing arbitrary code on the device, leading to full control.
• Data Exfiltration: Sensitive information stored on the device can be accessed and exfiltrated.
• Denial of Service (DoS): Attackers can disrupt the normal functioning of the device, leading to service outages.

3. Affected Systems and Software Versions

Affected Product: MAXTECH MAX-G866ac

Affected Version: 0.4.1_TBRO_20160314
