CVE-2025-7230
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on systems running vulnerable versions of INVT VT-Designer when users open malicious PM3 files. Attackers can achieve remote code execution in the context of the current process by exploiting type confusion during PM3 file parsing. Users of INVT VT-Designer who open untrusted PM3 files are affected.
💻 Affected Systems
- INVT VT-Designer
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the VT-Designer process, potentially leading to lateral movement, data theft, or ransomware deployment.
Likely Case
Local privilege escalation or system compromise when users open malicious PM3 files from untrusted sources, with attackers gaining control over the affected system.
If Mitigated
Limited impact with proper application sandboxing and user privilege restrictions, potentially containing the exploit to the application context.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and knowledge of PM3 file format structure. ZDI-CAN-25723 tracking suggests detailed research exists.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: Not provided in references
Restart Required: No
Instructions:
1. Monitor INVT official channels for security updates. 2. Check vendor website for VT-Designer updates. 3. Apply any available patches immediately. 4. Verify patch installation by testing with known safe PM3 files.
🔧 Temporary Workarounds
Restrict PM3 file handling
windowsConfigure system to open PM3 files only with trusted applications or in isolated environments
Use Windows Group Policy to restrict file associations for .pm3 files
Application sandboxing
allRun VT-Designer in restricted environment with limited privileges
🧯 If You Can't Patch
- Implement strict controls on PM3 file sources - only allow files from trusted, verified sources
- Use application whitelisting to prevent execution of unauthorized code and monitor for suspicious VT-Designer behavior
🔍 How to Verify
Check if Vulnerable:
Check VT-Designer version against vendor advisory when available. Test with controlled PM3 files in isolated environment.Check Version:
Check VT-Designer 'About' dialog or installation directory for version informationVerify Fix Applied:
Verify installed version matches patched version from vendor. Test file parsing functionality with various PM3 files.📡 Detection & Monitoring
Log Indicators:
- Unexpected VT-Designer crashes
- Suspicious child processes spawned from VT-Designer
- Multiple failed PM3 file parsing attempts
Network Indicators:
- Unusual outbound connections from VT-Designer process
- Downloads of PM3 files from untrusted sources
