CVE-2024-9719
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on affected Trimble SketchUp Viewer installations by tricking users into opening a malicious SKP file. The flaw is a use-after-free issue in SKP file parsing that enables code execution in the current process context. All users of vulnerable SketchUp Viewer versions are affected.
💻 Affected Systems
- Trimble SketchUp Viewer
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via remote code execution with user privileges, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Malicious actor gains code execution on user's workstation, enabling credential theft, data exfiltration, or installation of persistent malware.
If Mitigated
Limited impact due to application sandboxing, limited user privileges, or network segmentation preventing lateral movement.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file). Use-after-free vulnerabilities typically require specific memory manipulation knowledge.
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Disable SKP file association
allPrevent SketchUp Viewer from automatically opening SKP files
Windows: Control Panel > Default Programs > Associate a file type or protocol with a program > Change .skp association to another program or 'Ask each time'
macOS: Right-click SKP file > Get Info > Open with > Select different application
Application control policy
allBlock SketchUp Viewer execution via endpoint security controls
🧯 If You Can't Patch
- Implement application whitelisting to block SketchUp Viewer execution
- Use network segmentation to isolate systems running vulnerable software
- Educate users not to open SKP files from untrusted sources
- Deploy endpoint detection and response (EDR) to monitor for exploitation attempts
