CVE-2022-48360

7.5 HIGH

📋 TL;DR

This vulnerability in Huawei's facial recognition module involves improper file permission controls that could allow unauthorized access to sensitive facial recognition data. It affects Huawei devices running HarmonyOS with the facial recognition feature enabled. Exploitation could compromise user biometric confidentiality.

💻 Affected Systems

Products:
  • Huawei smartphones and tablets with facial recognition
Versions: HarmonyOS versions prior to security updates in March 2023
Operating Systems: HarmonyOS
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects devices with facial recognition feature enabled. Specific device models not detailed in provided references.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could access and exfiltrate facial recognition templates or biometric data, potentially enabling identity theft or unauthorized authentication bypass.

🟠

Likely Case

Local attackers with device access could read facial recognition configuration files or temporary data, compromising user privacy.

🟢

If Mitigated

With proper file permissions and access controls, only authorized system processes can access facial recognition data, maintaining confidentiality.

🌐 Internet-Facing: LOW - This appears to be a local file permission issue requiring physical or local access to the device.
🏢 Internal Only: MEDIUM - Malicious insiders or compromised local accounts could exploit this to access biometric data.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation likely requires local access to the device and knowledge of file system structure. No public exploit details available.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: HarmonyOS security updates released in March 2023

Vendor Advisory: https://consumer.huawei.com/en/support/bulletin/2023/3/

Restart Required: Yes

Instructions:

1. Check for system updates in device Settings > System & updates > Software update. 2. Install available security updates. 3. Restart device when prompted.

🔧 Temporary Workarounds

Disable facial recognition

all

Temporarily disable facial recognition feature to prevent exploitation

Restrict physical access

all

Implement physical security controls to prevent unauthorized device access

🧯 If You Can't Patch

  • Disable facial recognition authentication and use alternative methods (PIN, password, fingerprint)
  • Implement strict physical security controls and monitor for unauthorized device access

🔍 How to Verify

Check if Vulnerable:

Check HarmonyOS version in Settings > About phone > HarmonyOS version. If version predates March 2023 security updates, device may be vulnerable.

Check Version:

Not applicable - check via device Settings interface

Verify Fix Applied:

Verify HarmonyOS version includes March 2023 security updates. Check Settings > System & updates > Security update details.
