Unauthenticated backup download via installer URL disclosure

Published Aug 22, 2022 · Updated Aug 3, 2024

Information disclosure in Snap Creek LLC Duplicator before 1.4.7 allows remote attackers to download full site backups without authentication. The main.installer.php endpoint returns the randomized installer filename when is_daws=1 is supplied, and replacing the filename suffix yields the archive URL. The endpoint exposes the backup only after an administrator has run the installer at least once, but the archive can contain the site files and database.
