CVE-2025-7226 is a high-severity vulnerability classified under CWE-787 (Out-of-bounds Write) affecting INVT's HMITool software, specifically version 7.1.011. The vulnerability arises from improper validation of user-supplied data during the parsing of VPM files, which leads to a write operation beyond the allocated buffer boundaries. This memory corruption flaw can be exploited remotely by an attacker who convinces a user to open a maliciously crafted VPM file or visit a malicious webpage that triggers the vulnerable parsing logic. Successful exploitation allows the attacker to execute arbitrary code within the context of the current process, potentially leading to full compromise of the affected system. The vulnerability requires user interaction (UI:R) but does not require prior authentication (PR:N). The CVSS v3.0 score is 7.8, reflecting high impact on confidentiality, integrity, and availability. Although no public exploits are currently known in the wild, the nature of the vulnerability and its remote code execution capability make it a significant threat. The lack of a patch at the time of disclosure increases the urgency for mitigation. INVT HMITool is typically used in industrial automation and HMI (Human Machine Interface) environments, which are critical for operational technology (OT) systems.

For European organizations, especially those operating in industrial automation, manufacturing, energy, and critical infrastructure sectors, this vulnerability poses a serious risk. Exploitation could lead to unauthorized control or disruption of industrial processes, causing operational downtime, safety hazards, and potential physical damage. Confidentiality breaches could expose sensitive operational data or intellectual property. Integrity violations might result in manipulation of control commands or process data, undermining system reliability. Availability impacts could disrupt production lines or critical services. Given the reliance on HMITool in industrial environments, successful exploitation could have cascading effects on supply chains and critical infrastructure resilience within Europe. The requirement for user interaction means social engineering or phishing campaigns targeting European industrial operators could be a likely attack vector.

1. Immediate mitigation should include restricting access to INVT HMITool installations and limiting the opening of VPM files from untrusted sources. 2. Implement network segmentation to isolate industrial control systems running HMITool from general IT networks and the internet to reduce exposure. 3. Employ application whitelisting and endpoint protection solutions capable of detecting anomalous behavior related to buffer overflows or code execution attempts. 4. Educate users and operators about the risks of opening unsolicited or suspicious files and visiting untrusted websites, emphasizing the social engineering aspect of this vulnerability. 5. Monitor logs and network traffic for unusual activity indicative of exploitation attempts. 6. Coordinate with INVT for timely patch releases and apply updates as soon as they become available. 7. Consider deploying virtual patching or intrusion prevention systems with custom signatures targeting this vulnerability if patches are delayed. 8. Conduct regular security assessments and penetration testing focused on industrial control systems to identify and remediate similar vulnerabilities proactively.
