CVE-2022-28807
📋 TL;DR
An out-of-bounds read vulnerability in Open Design Alliance Drawings SDK allows attackers to execute arbitrary code when processing malicious DWG files in recovery mode. This affects applications using the vulnerable SDK to handle CAD drawings. Attackers can exploit this by tricking users into opening specially crafted DWG files.
💻 Affected Systems
- Open Design Alliance Drawings SDK
- Applications using ODA Drawings SDK

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application using the SDK, potentially leading to full system compromise.
Likely Case
Application crash or limited information disclosure from memory reads, with potential for RCE if combined with other vulnerabilities.
If Mitigated
No impact if patched or if recovery mode is disabled.
🎯 Exploit Status
Requires user interaction to open malicious DWG file. Exploitation depends on memory layout and application specifics.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2023.2 and later
Vendor Advisory: https://www.opendesign.com/security-advisories
Restart Required: Yes
Instructions:
1. Identify applications using ODA Drawings SDK. 2. Update SDK to version 2023.2 or later. 3. Recompile applications with updated SDK. 4. Restart affected applications/services.
🔧 Temporary Workarounds
Disable recovery mode
allConfigure applications to not use recovery mode when opening DWG files
File type restrictions
allBlock or sandbox DWG file processing in vulnerable applications
🧯 If You Can't Patch
- Implement application sandboxing to limit impact of potential code execution
- Use file integrity monitoring to detect unexpected application crashes or modifications
🔍 How to Verify
Check if Vulnerable:
Check application documentation or contact vendor to confirm ODA SDK version. Version below 2023.2 is vulnerable.Check Version:
Application-specific - check vendor documentation for version query methodsVerify Fix Applied:
Confirm ODA SDK version is 2023.2 or later. Test with known safe DWG files in recovery mode.📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing DWG files
