CVE-2024-41160
📋 TL;DR
This CVE describes a use-after-free vulnerability in OpenHarmony that allows a local attacker to escalate common permissions to root and leak sensitive information. It affects OpenHarmony v4.1.0 and earlier versions. Attackers need local access to exploit this vulnerability.
💻 Affected Systems
- OpenHarmony
📦 What is this software?
Openharmony by Openatom
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root access, allowing installation of persistent malware, data exfiltration, and disabling of security controls.
Likely Case
Local privilege escalation leading to unauthorized access to sensitive data and system resources.
If Mitigated
Limited impact if proper access controls and privilege separation are implemented, though information leakage may still occur.
🎯 Exploit Status
Requires local access and some technical knowledge to exploit the use-after-free condition.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OpenHarmony v4.1.1 or later
Vendor Advisory: https://gitee.com/openharmony/security/blob/master/zh/security-disclosure/2024/2024-09.md
Restart Required: Yes
Instructions:
1. Check current OpenHarmony version. 2. Update to OpenHarmony v4.1.1 or later. 3. Reboot the system. 4. Verify the update was successful.
🔧 Temporary Workarounds
Restrict local user access
allLimit local user accounts and implement strict access controls to reduce attack surface.
Implement privilege separation
allEnsure applications run with minimal necessary privileges to limit impact of potential escalation.
🧯 If You Can't Patch
- Implement strict access controls and monitor for suspicious local activity.
- Isolate affected systems from critical networks and data.
🔍 How to Verify
Check if Vulnerable:
Check OpenHarmony version: cat /etc/os-release or equivalent system command.Check Version:
cat /etc/os-release | grep VERSIONVerify Fix Applied:
Verify system is running OpenHarmony v4.1.1 or later using version check command.📡 Detection & Monitoring
Log Indicators:
- Unexpected privilege escalation events
- Suspicious process creation with elevated privileges
- Access to sensitive system files by non-root users
Network Indicators:
- Unusual outbound connections from system following local user activity
SIEM Query:
Process creation where parent process is non-root and child process runs as root, or file access patterns showing non-privileged users accessing sensitive system files.
