Forged firmware installation via hard-coded magic and MD5
Published Oct 27, 2025 · Updated Oct 27, 2025
Improper firmware signature verification in D-Link DAP-2695 2.00RC13 allows remote authenticated users to install forged firmware. The rgbin sub_40C6B8 routine accepts a disclosed hard-coded magic value, while sub_40C51C verifies the image with forgeable MD5. Administrative firmware-update access and a crafted image are required; successful bypass permits attacker-controlled firmware to run on the access point.
