CVE-2025-7226
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on systems running vulnerable versions of INVT HMITool by tricking users into opening malicious VPM files or visiting malicious web pages. The flaw exists in how the software parses VPM files, enabling attackers to write beyond allocated buffer boundaries. Users of INVT HMITool who process untrusted VPM files are at risk.
💻 Affected Systems
- INVT HMITool
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control of the affected system, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Attacker executes malicious code with the privileges of the current user, potentially installing malware, stealing credentials, or establishing persistence on the system.
If Mitigated
Limited impact due to proper file validation, user awareness training, and restricted execution privileges, potentially resulting in application crash only.
🎯 Exploit Status
Exploitation requires user interaction but leverages common buffer overflow techniques. ZDI-CAN-25048 identifier suggests detailed research exists.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://www.zerodayinitiative.com/advisories/ZDI-25-477/
Restart Required: Yes
Instructions:
1. Check INVT official website for security updates
2. Download and install the latest version of HMITool
3. Restart the application and any related services
4. Verify the patch is applied correctly
🔧 Temporary Workarounds
Restrict VPM file processing
allBlock or restrict processing of VPM files from untrusted sources
User awareness training
allTrain users not to open VPM files from unknown or untrusted sources
🧯 If You Can't Patch
- Implement application whitelisting to prevent execution of unauthorized code
- Run HMITool with minimal user privileges to limit potential damage
🔍 How to Verify
Check if Vulnerable:
Check HMITool version against vendor's patched version list. If processing VPM files from untrusted sources, assume vulnerable.Check Version:
Check Help > About in HMITool application or consult vendor documentationVerify Fix Applied:
Verify installed version matches or exceeds vendor's patched version. Test with known safe VPM files to ensure functionality.📡 Detection & Monitoring
Log Indicators:
- Application crashes with memory access violations
- Unusual process creation from HMITool executable
- Failed attempts to access protected memory regions
Network Indicators:
- Downloads of VPM files from suspicious sources
- Outbound connections from HMITool to unknown IPs post-file processing
SIEM Query:
Process creation where parent_process contains 'HMITool' AND (command_line contains '.vpm' OR command_line contains unusual parameters)
