CVE-2023-22669

7.8 HIGH

📋 TL;DR

This is a heap-based buffer overflow vulnerability in Open Design Alliance Drawings SDK that allows remote code execution when processing malicious DWG files. Attackers can exploit this by crafting specially designed DWG files to execute arbitrary code in the context of the application using the SDK. Any software using vulnerable versions of the ODA Drawings SDK for DWG file processing is affected.

💻 Affected Systems

Products:
  • Open Design Alliance Drawings SDK
  • Any software using ODA Drawings SDK for DWG file processing
Versions: All versions before 2023.6
Operating Systems: Windows, Linux, macOS
Default Config Vulnerable: ⚠️ Yes
Notes: Affects all applications that use the vulnerable SDK to parse DWG files, regardless of operating system.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full remote code execution with the privileges of the application processing the DWG file, potentially leading to complete system compromise, data theft, or ransomware deployment.

🟠

Likely Case

Application crash leading to denial of service, with potential for limited code execution depending on exploit sophistication and memory protections.

🟢

If Mitigated

Application crash with no code execution if modern exploit mitigations (ASLR, DEP) are effective, but still causing service disruption.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Exploitation requires user interaction to open a malicious DWG file, but no authentication is needed. The vulnerability is in file parsing logic.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2023.6 or later

Vendor Advisory: https://www.opendesign.com/security-advisories

Restart Required: Yes

Instructions:

1. Identify all applications using ODA Drawings SDK. 2. Update to ODA Drawings SDK version 2023.6 or later. 3. Rebuild/redeploy affected applications. 4. Restart services using the updated SDK.

🔧 Temporary Workarounds

File Type Restriction

all

Block or restrict processing of DWG files from untrusted sources

Application Sandboxing

all

Run applications that process DWG files in restricted environments or containers

🧯 If You Can't Patch

  • Implement strict file validation and only accept DWG files from trusted sources
  • Deploy application control solutions to prevent execution of unauthorized code

🔍 How to Verify

Check if Vulnerable:

Check the version of ODA Drawings SDK used by your applications. If version is earlier than 2023.6, you are vulnerable.

Check Version:

Check application documentation or contact software vendors to determine ODA SDK version used.

Verify Fix Applied:

Verify that all applications are using ODA Drawings SDK version 2023.6 or later and test DWG file processing functionality.

📡 Detection & Monitoring

Log Indicators:

  • Application crashes when processing DWG files
  • Memory access violation errors in application logs
  • Unexpected process termination

Network Indicators:

  • Unusual network connections from applications that process DWG files
  • Outbound connections following DWG file processing

SIEM Query:

source="application_logs" AND ("access violation" OR "segmentation fault" OR "buffer overflow") AND "DWG"
