Vulnerability from fkie_nvd - Published: 2019-01-02 18:29 - Updated: 2026-06-17 01:52

Severity

9.8 (Critical) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

An issue was discovered on August Connect devices. Insecure data transfer between the August app and August Connect during configuration allows attackers to discover home Wi-Fi credentials. This data transfer uses an unencrypted access point for these credentials, and passes them in an HTTP POST, using the AugustWifiDevice class, with data encrypted with a fixed key found obfuscated in the app.
