Published Jun 24, 2024 · Updated Mar 19, 2025

Path disclosure in Virto Bulk File Download 5.5.44 for SharePoint 2019 allows remote attackers to read full server pathnames via archive requests. The Download.ashx archive action exposes full filesystem pathnames in its response instead of withholding internal path information. No authentication or user interaction is required; the reported consequence is limited to pathname disclosure, with no direct file-content access.
