The specific API in TCBServiSign Windows Version from CHANGING Information Technology does not properly validate server-side input. When a user visits a spoofed website, unauthenticated remote attackers can modify the `HKEY_CURRENT_USER` registry to execute arbitrary commands.
Solution:
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
