Is this vulnerability remotely exploitable over the internet?

It can be, if the router's management interface is exposed to the internet or accessible from an attacker-controlled network segment. If management is strictly limited to a private, well-controlled network, exposure is reduced but still present for insiders or compromised hosts.

Does an attacker need valid credentials to exploit this issue?

No. The vulnerability specifically involves an unauthenticated endpoint; an attacker only needs network access to the router's web interface to attempt to download the configuration file.

What is the safest general fix pattern for this type of flaw?

Apply strong access control to all configuration export and backup functions, ensuring they require a valid, privileged admin session and, ideally, additional confirmation. At the same time, remove plaintext credentials from configuration files by using hashed password storage and masking or omitting secrets in exported data.
