Unauthenticated memory corruption via set_ws_action overflow
Published Mar 22, 2025 · Updated Mar 24, 2025
Heap-based buffer overflow in D-Link DAP-1620 1.03 allows remote attackers to corrupt memory through the /dws/api/ path handler. The set_ws_action function mishandles attacker-controlled request data and writes beyond a heap allocation; the exact request parameter is undisclosed. No authentication or user interaction is required, and successful exploitation can compromise device data or interrupt its service.
