CVE-2024-0014

7.8 HIGH

📋 TL;DR

This vulnerability in Android's update system allows attackers to trigger malicious configuration updates without user interaction, leading to local privilege escalation. It affects Android devices with vulnerable versions of the update framework, potentially allowing attackers to gain elevated system privileges.

💻 Affected Systems

Products:
  • Android OS
Versions: Android versions prior to February 2024 security patch
Operating Systems: Android
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the Android update framework component; exploitation requires initial app installation or physical access.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device compromise with system-level privileges, enabling installation of persistent malware, data theft, and bypassing security controls.

🟠

Likely Case

Local privilege escalation allowing attackers to install malicious apps with elevated permissions, modify system settings, or access protected data.

🟢

If Mitigated

Limited impact if devices are patched, have strict app installation controls, and use verified boot mechanisms.

🌐 Internet-Facing: LOW - This is primarily a local privilege escalation vulnerability requiring local access or malicious app installation.
🏢 Internal Only: HIGH - Once an attacker gains initial access (via malicious app), they can exploit this to escalate privileges without additional user interaction.

🎯 Exploit Status

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

Requires initial access to install malicious app or physical device access; no user interaction needed for privilege escalation once initial access is achieved.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: February 2024 Android Security Patch Level or later

Vendor Advisory: https://source.android.com/security/bulletin/2024-02-01

Restart Required: Yes

Instructions:

1. Check for system updates in Settings > System > System update. 2. Install February 2024 security patch or later. 3. Restart device after installation completes.

🔧 Temporary Workarounds

Disable unknown sources

android

Prevent installation of apps from unknown sources to block initial attack vector

Settings > Security > Install unknown apps > Disable for all apps

Enable Google Play Protect

android

Use Google's built-in malware scanning for additional protection

Settings > Security > Google Play Protect > Scan device for security threats

🧯 If You Can't Patch

  • Restrict app installation to Google Play Store only
  • Implement mobile device management (MDM) with strict app whitelisting

🔍 How to Verify

Check if Vulnerable:

Check Android security patch level: Settings > About phone > Android version > Security patch level. If before February 2024, device is vulnerable.

Check Version:

adb shell getprop ro.build.version.security_patch

Verify Fix Applied:

Verify security patch level shows February 2024 or later date.
