Is this vulnerability remotely exploitable over the internet?

Not directly. Exploitation requires the attacker to control or spoof a Wi-Fi access point whose SSID is visible to the OpenWrt device and for an authenticated LuCI user to open the wireless scan modal in a browser.

Does an attacker need administrative access to the router to exploit this?

No router login is required for the attacker; they only need to influence the SSID being broadcast. However, exploitation affects the browser of a user already authenticated to LuCI, and the impact is constrained by that user's privileges.

What is the safest general fix pattern for developers?

The most robust fix is to treat all external strings, including SSIDs, as untrusted and always perform context-appropriate output encoding before rendering them. Avoid passing unescaped data into `innerHTML` and instead use DOM APIs that handle text safely.
