CVE-2025-0304
📋 TL;DR
This CVE describes a use-after-free vulnerability in OpenHarmony that allows a local attacker to escalate common permissions to root privileges and leak sensitive information. It affects OpenHarmony v4.1.2 and earlier versions. The vulnerability requires local access to the system.
💻 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 that should be restricted.
If Mitigated
Limited impact if proper access controls and privilege separation are implemented, though information leakage may still occur.
🎯 Exploit Status
Exploitation requires local access and knowledge of the use-after-free condition. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OpenHarmony v4.1.3 or later
Vendor Advisory: https://gitee.com/openharmony/security/blob/master/zh/security-disclosure/2025/2025-02.md
Restart Required: No
Instructions:
1. Check current OpenHarmony version. 2. Update to OpenHarmony v4.1.3 or later. 3. Apply the security patch through official update channels. 4. Verify the update was successful.
🔧 Temporary Workarounds
Restrict local user access
allLimit local user accounts to only trusted personnel and implement strict access controls
Implement privilege separation
allEnsure proper privilege separation between user processes and system processes
🧯 If You Can't Patch
- Implement strict access controls to limit local user access to vulnerable systems
- Monitor for suspicious privilege escalation attempts and implement enhanced logging
🔍 How to Verify
Check if Vulnerable:
Check OpenHarmony version using 'getprop ro.build.version.ohos' command. If version is 4.1.2 or earlier, the system is vulnerable.Check Version:
getprop ro.build.version.ohosVerify Fix Applied:
After updating, verify the version is 4.1.3 or later using 'getprop ro.build.version.ohos' command.📡 Detection & Monitoring
Log Indicators:
- Unexpected privilege escalation events
- Processes running with unexpected root privileges
- Access to sensitive system files by non-privileged users
Network Indicators:
- Unusual outbound connections from system processes
