CVE-2025-7224
📋 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 without proper input validation, leading to buffer overflow conditions. Users of INVT HMITool who process VPM files are affected.
💻 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
Local privilege escalation leading to unauthorized access to sensitive HMI data and potential disruption of industrial control operations.
If Mitigated
Limited impact with proper network segmentation and user awareness preventing malicious file execution.
🎯 Exploit Status
Exploitation requires social engineering to deliver malicious VPM files but technical complexity is moderate once file is opened.
