Recommendation: Monitor — no exploitation signal at the moment.

Rejetto HFS 3.0.0 through 3.2.0 does not escape file names in its fallback "basic" web listing, and this listing can be forced by any browser via the ?get=basic parameter. A user with upload permission - or an anonymous user on servers with an open upload folder - can store a file whose name contains script that executes in the browser of anyone viewing the listing.
