Technical details
The SmartLife application generates authentication parameters at runtime that are insufficiently protected, allowing an attacker to extract them. By replaying these parameters against the /account/verify.serv backend endpoint, an attacker can enumerate account IDs by email address; combined with spoofed authentication, this enables unauthorized password reset without knowledge of the original credentials.
