Is this vulnerability remotely exploitable from the internet?

By design it is LAN-adjacent: exploitation typically requires access to the internal network where the router's LAN interface is reachable. However, if the LAN is bridged or exposed (for example, via misconfigured remote access or VPN), attackers outside the physical premises may be able to reach the SSH service.

What level of access does an attacker gain if they exploit this?

An attacker obtains a root shell on the router, granting full administrative control over the device, its configuration, and its handling of network traffic.

What is the safest general fix pattern?

The robust fix pattern is to enforce strong, mandatory authentication on all administrative services and provide administrators with the ability to disable or tightly restrict remote management interfaces such as SSH. Devices should ship with secure defaults, including unique strong credentials or initial setup flows that require credential configuration.
