Unauthenticated file upload via uploadify.php
Published Jul 21, 2026 · Updated Jul 21, 2026
Unrestricted file upload in D-Link DNS-320 1.0.2 allows remote attackers to write attacker-chosen files via uploadify.php. The published record identifies /photo_center/php/uploadify.php and a crafted Malicious Handler argument but does not disclose the underlying function or validation failure. No authentication or user interaction is required; the grounded consequence is file placement on the NAS, not demonstrated code execution.
