# This script demonstrates the logic of exploiting improper access control in Microsoft Office Word.
# Note: This is a simulation based on the vulnerability description.

# In a real attack, the attacker might use a crafted file or specific API calls.

# Check if the target process is running (Simulation)
# if target_process in running_processes:
# print(f"[+] Target {target_process} detected.")

# Since UI:N is not required, this can be scripted.
