CVE-2023-31904Public exploitNetwork attack vector

Unauthenticated file disclosure via path traversal

Published May 17, 2023 · Updated Jan 21, 2025

Local file inclusion in Savysoda Wifi HD Wireless Disk Drive 11 allows remote attackers to read local files through crafted HTTP paths. The built-in HTTP file server accepts repeated ../ segments in the request path without restricting the resolved path and returns the selected file as a download. No authentication or user interaction is required; exposure is limited to files readable by the app while its HTTP service is reachable.
