Overview

The vulnerability, coded as CVE-2025-27460, is a significant security flaw that arises from the lack of full volume encryption in the device’s hard drives. This vulnerability primarily affects devices operating Windows OS, where BitLocker or similar encryption features are not utilized. The gravity of this vulnerability lies in its potential to compromise systems and leak sensitive data, especially when an attacker obtains physical access to the device.

How the Exploit Works

This exploit takes advantage of the lack of full volume encryption on the device’s hard drives. In the case of this vulnerability, an attacker with physical access to the device can use an alternative operating system to interact with the hard drives directly, bypassing the Windows login mechanism completely. This allows the attacker to read from and write to all files on the hard drives, leading to potential system compromise and data leakage.

Conceptual Example Code

The exploit does not require any coding as it is based on physical access and manipulation of the device’s hard drive. The attacker might use a bootable USB device with an alternative operating system to bypass the Windows login, as shown in the conceptual steps below:
1. Plug in a bootable USB device with alternative OS.
2. Restart the device and boot from the USB.
3. Access the internal hard drive contents directly.
4. Read or modify files as needed.

# Example shell commands on the alternative OS
cd /media/hard_drive
ls -la # list all files
cat /path/to/sensitive/file # read a sensitive file
echo "malicious_data" > /path/to/affected/file # write to a file

This would effectively compromise the system and potentially leak sensitive data.
