CVE-2024-56452
📋 TL;DR
This vulnerability allows attackers to crash applications by providing malicious glTF 3D model files that trigger buffer overflows during parsing. It affects any software using the vulnerable 3D engine module, particularly applications that load user-supplied 3D models.
💻 Affected Systems
- Huawei devices and applications using the vulnerable 3D engine module
📦 What is this software?
Harmonyos by Huawei
⚠️ Risk & Real-World Impact
Worst Case
Complete application crash leading to denial of service, potentially affecting entire systems if the application is critical infrastructure.
Likely Case
Application instability or crashes when processing specially crafted glTF files, disrupting user workflows.
If Mitigated
Minimal impact with proper input validation and sandboxing of 3D model processing.
🎯 Exploit Status
Exploitation requires crafting malicious glTF files and getting them processed by vulnerable software. No public exploit details available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Huawei security bulletin for specific patched versions
Vendor Advisory: https://consumer.huawei.com/en/support/bulletin/2025/1/
Restart Required: Yes
Instructions:
1. Check Huawei security bulletin for affected device models. 2. Apply latest security updates via device settings or HiSuite. 3. Restart device after update completion.
🔧 Temporary Workarounds
Disable glTF file processing
allPrevent applications from loading glTF 3D model files if not required
Input validation for 3D files
allImplement server-side validation of glTF files before processing
🧯 If You Can't Patch
- Restrict user uploads of 3D model files to trusted sources only
- Isolate 3D processing in sandboxed environments with resource limits
🔍 How to Verify
Check if Vulnerable:
Check device/software version against Huawei security bulletin. Test with known safe glTF files for crashes.Check Version:
Android: Settings > About phone > Build number. Software: Check application/about section for version info.Verify Fix Applied:
Verify software version is updated to patched version listed in Huawei advisory. Test glTF file processing functionality.📡 Detection & Monitoring
Log Indicators:
- Application crashes during 3D model loading
- Memory access violation errors in logs
