The SIMATIC WinCC DataMonitor web application of the affected products allows an authenticated user with network access to the WinCC DataMonitor application to upload arbitrary ASPX code.
Successful exploitation requires no user interaction and may impact the confidentiality, integrity, and availability of the affected device. The vulnerability is relevant only in situations where an attacker has access via the web interface but not to the directory structure.
