Is this vulnerability remotely exploitable over the internet?

It can be, depending on how the router is deployed. If the management interface or relevant API endpoints are exposed to the internet via remote administration features or port forwarding, attackers on the internet may exploit it. If access is restricted to the local network, the threat is limited to adversaries with LAN access or those who have already breached the internal environment.

What level of access does an attacker need to exploit this issue?

An attacker needs network access to the router's web interface and the ability to send requests to the endpoint that invokes `macAddrClone`. No valid credentials may be required if the endpoint is accessible without authentication or if other flaws or weak credentials allow bypassing authentication.

What is the safest general fix pattern for developers of similar devices?

The safest pattern is to avoid shell-based command composition altogether for operations driven by web input. Use high-level system APIs or libraries that encapsulate the required functionality, or strictly parameterized command execution APIs that never interpret user input as shell syntax. Combine this with strong allowlists for parameters and rigorous input validation.
