CVE-2020-7998Public exploitNetwork attack vector

Arbitrary file upload via FTP path traversal

Published Jan 28, 2020 · Updated Aug 4, 2024

Arbitrary file upload in Super File Explorer 1.0.1 for iOS allows remote attackers to write files through its FTP service. The FTP server accepts arbitrary credentials and permits parent-directory traversal from the app directory into a hidden developer path, where uploaded files are stored outside the intended root. The service must first be enabled through Remote Manager, but its default passwordless configuration exposes reachable device paths without a valid application account.
