CVE-2025-13453
📋 TL;DR
A physical security vulnerability in certain ThinkPlus USB drives allows unauthorized data access when an attacker has physical possession of the device. This affects users of vulnerable ThinkPlus USB drive models who store sensitive data on these devices. The vulnerability enables reading stored data without proper authentication.
💻 Affected Systems
- ThinkPlus USB drives (specific models not detailed in reference)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Sensitive data stored on the USB drive is fully compromised, including confidential documents, credentials, or personal information, leading to data breaches or identity theft.
Likely Case
Unauthorized reading of stored files when the USB drive is lost, stolen, or accessed by unauthorized personnel in physical proximity.
If Mitigated
Minimal impact if drives are encrypted, physically secured, or contain only non-sensitive data.
🎯 Exploit Status
Exploitation requires physical access to the USB drive. No authentication bypass needed once physical access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Vendor Advisory: https://iknow.lenovo.com.cn/detail/436983
Restart Required: No
Instructions:
No firmware patch available. Replace affected USB drives with secure models or implement encryption workarounds.
🔧 Temporary Workarounds
Enable Full Disk Encryption
allUse operating system or third-party encryption to protect data on USB drives
Windows: Use BitLocker To Go
Linux: Use LUKS encryption
macOS: Use FileVault
Use Encrypted Container Files
allStore sensitive data in encrypted archive files (e.g., VeraCrypt, 7-Zip with encryption)
VeraCrypt: Create encrypted volume
7-Zip: 7z a -p archive.7z files/ -mhe
🧯 If You Can't Patch
- Replace vulnerable ThinkPlus USB drives with secure models from different manufacturers
