A vulnerability has been identified in SIMATIC MV400 family (All Versions < V7.0.6). Communication with the device is not encrypted. Data transmitted between the device and the user can be obtained by an attacker in a privileged network position. The security vulnerability can be exploited by an attacker in a privileged network position which allows eavesdropping the communication between the affected device and the user. The user must invoke a session. Successful exploitation of the vulnerability compromises confidentiality of the data transmitted.
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
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.
