CVE-2013-3960Public exploitNetwork attack vector

Sandbox file access and deletion via unchecked paths

Published Jan 24, 2020 · Updated Aug 6, 2024

Missing authorization in Easytime Studio Easy File Manager 1.1 allows remote authenticated users to browse and delete sandbox files. The iOS app's HTTP server accepts a modified path in a session-bearing GET request and exposes file-system locations outside the personal-file view. The HTTP server must be enabled and reachable over Wi-Fi, and a valid session is required; exploitation reads or deletes sandbox-accessible files.
