IoT Haat Smart Plug IH-IN-16A-S IH-IN-16A-S v5.16.1 suffers from Insufficient Session Expiration. The lack of validation of the authentication token at the IoT Haat during the Access Point Pairing mode leads the attacker to replay the Wi-Fi packets and forcefully turn off the access point after the authentication token has expired.
According to WASC, “Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization.”
