Name of the Vulnerable Software and Affected Versions Rejetto HFS versions 3.0.0 through 3.2.0

Description Stored Cross-Site Scripting occurs because the software fails to escape file names in its fallback basic web listing. This listing can be triggered by any browser using the ?get=basic parameter. An attacker with upload permissions, or an anonymous user on servers with an open upload folder, can upload a file with a name containing a malicious script that executes in the browser of any user viewing the listing.

Recommendations Update Rejetto HFS to a version later than 3.2.0. Restrict upload permissions or close open upload folders to prevent unauthorized file storage.
