The Kankun Smart Socket device and mobile application uses a hardcoded AES 256 bit key, which makes it easier for remote attackers to (1) obtain sensitive information by sniffing the network and (2) obtain access to the device by encrypting messages.
Weaknesses in this category are related to the design and implementation of data confidentiality and integrity. Frequently these deal with the use of encoding techniques, encryption libraries, and hashing algorithms. The weaknesses in this category could lead to a degradation of the quality data if they are not addressed.
