Is this vulnerability remotely exploitable?

Yes. A remote attacker can exploit the vulnerability by crafting a malicious URL that targets the `/?Function=Groups` endpoint with specially crafted `selectgroup` or `gn` parameters and then convincing a victim to visit that URL in a browser.

Does an attacker need to be authenticated to exploit this issue?

Not necessarily. The technical exploit is based on reflected output in the browser. However, the impact is greatest when the victim is an authenticated user with meaningful permissions in the Global Facilities Management Software, because the injected script runs with that user's session context.

What is the safest general fix pattern for this XSS vulnerability?

The most reliable approach is to ensure all user-controlled data, including `selectgroup` and `gn`, is passed through consistent, context-aware output encoding mechanisms before being embedded in any HTML, attribute, or script context, ideally leveraging a templating system that auto-escapes by default.
