CVE-2024-56451
📋 TL;DR
An integer overflow vulnerability in the glTF model loading component of a 3D engine module allows attackers to cause denial of service by crashing the application. This affects systems using the vulnerable 3D engine module to process glTF files. The impact is primarily on availability rather than confidentiality or integrity.
💻 Affected Systems
- Huawei products 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 disrupting 3D rendering services or applications that rely on this engine module.
Likely Case
Application instability or crashes when processing maliciously crafted glTF files, affecting user experience and service availability.
If Mitigated
Minimal impact with proper input validation and memory protection mechanisms in place.
🎯 Exploit Status
Exploitation requires crafting a malicious glTF file with specific integer overflow triggers; attacker needs to get victim to load the file.
🛠️ 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: No
Instructions:
1. Review Huawei security advisory for affected products. 2. Apply vendor-provided patches or updates. 3. Verify patch installation and test glTF file processing functionality.
🔧 Temporary Workarounds
Restrict glTF file processing
allDisable or restrict loading of glTF 3D model files in affected applications where possible.
Application-specific configuration changes required
Implement file validation
allAdd validation checks for glTF files before processing to detect malformed inputs.
Custom validation logic implementation needed
🧯 If You Can't Patch
- Implement network segmentation to isolate systems using the vulnerable 3D engine
- Monitor for abnormal application crashes or glTF file processing failures
🔍 How to Verify
Check if Vulnerable:
Check if your system uses the affected Huawei 3D engine module and processes glTF files; review Huawei advisory for specific version checks.Check Version:
System-specific command to check software version; consult product documentation.Verify Fix Applied:
After patching, test with known safe glTF files to ensure functionality remains, and verify no crashes occur with edge-case file inputs.📡 Detection & Monitoring
Log Indicators:
- Application crashes during glTF file loading
- Memory allocation errors in 3D engine logs
- Failed glTF parsing attempts
Network Indicators:
- Unusual glTF file transfers to affected systems
- Increased error responses from 3D processing services
SIEM Query:
search 'application_crash' AND 'glTF' OR '3D_engine' within relevant time windows
