CVE-2024-9939Public exploitNetwork attack vector

Unauthenticated file read via forged state cookies

Published Jan 8, 2025 · Updated May 20, 2026

Path traversal in Iptanus File Upload 4.24.13 and earlier allows remote attackers to read arbitrary server files without authentication. wfu_file_downloader.php trusts cookie-backed download-ticket expiry and file-storage values, then opens the supplied path without restricting it to an allowed directory. Direct network access to the downloader is sufficient; successful requests disclose any file readable by the web-server process.
