CVE-2021-46820Network attack vector

Authenticated file deletion via unvalidated image path

Published Jun 16, 2022 · Updated Aug 4, 2024

Arbitrary file deletion in XOS-Shop xos_shop_system 1.0.9 allows remote authenticated users to delete server files via an admin request. /shop/admin/categories.php trusts current_manufacturer_image as a deletion target without constraining it to an expected image path. A low-privileged authenticated session is required; deletion extends to any file writable by the PHP process, including .htaccess.
