Zizai Tech Nut contains multiple vulnerabilities including sensitive information exposure and missing authentication.


CWE-313: Cleartext Storage in a File or on Disk - CVE-2016-6547

The Nut mobile app stores the account password used to authenticate to the cloud API in cleartext in the cache.db file.

CWE-200: Information Exposure - CVE-2016-6548
The Nut mobile app makes requests via HTTP instead of HTTPS. These requests contain the user's authenticated session token with the URL. An attacker can capture these requests and reuse the session token to gain full access the user's account.

The Nut device allows unauthenticated Bluetooth pairing, which enables unauthenticated connected applications to write data to the device name attribute.

The CVSS Score below represents CVE-2016-6548

The CERT/CC is currently unaware of a practical solution to this problem.
