CVE-2025-3442

Wi-Fi credential disclosure via cleartext firmware storage

Published Apr 9, 2025 · Updated Apr 11, 2025

Cleartext credential storage in TP-Link Tapo H200 V1 firmware 1.4.0 and earlier allows physically proximate attackers to read Wi-Fi credentials. The device firmware embeds the configured Wi-Fi credentials as plaintext binary data rather than protecting them with encryption. Exploitation requires physical access to extract and analyze the firmware image, and the disclosed consequence is exposure of the hub's stored network credentials.
