Summary

The SmartLife app dynamically generates brand-new authentication parameters within its runtime process. With the obtained parameters, attackers can directly invoke the backend interface /account/verify.serv to determine whether a target email address is registered for a SmartLife account, and if the account exists, the real backend account ID can also be retrieved.

Risk Assessment

Attackers can enumerate registered accounts and obtain their identifiers, enabling user profiling and providing a basis for further attacks such as phishing or account takeover.

Recommendation

Restrict unauthenticated access to the /account/verify.serv interface and implement controls to prevent mass account existence checks and exposure of backend account IDs.
