CVE-2020-6007Public exploit

Code execution via unchecked ZCL string copy

Published Jan 23, 2020 · Updated Aug 4, 2024

Heap-based buffer overflow in Signify Philips Hue Bridge 2.X through 1935144020 allows adjacent attackers to execute code via Zigbee. CONFIGURE_DEVICES_ReceivedAttribute copies an attacker-controlled ZCL string length into a fixed 43-byte heap buffer without checking its bounds. Exploitation requires Zigbee radio proximity and user-initiated bulb commissioning; successful code execution compromises the bridge and can expose its IP network.
