CVE-2024-46041Public exploit

Authentication bypass via provisioning token replay

Published Oct 7, 2024 · Updated Oct 7, 2024

Authentication bypass in IoT Haat Smart Plug IH-IN-16A-S 5.16.1 allows attackers to impersonate a user via provisioning Wi-Fi. During access-point pairing, the provisioning flow accepts a replayed captured packet after its legitimate authentication token is replaced with an attacker-controlled token. The attacker must be within Wi-Fi range and capture provisioning traffic; public material does not identify the commands or data reachable after bypass.
