Description Preview
Overview
This vulnerability exists in Microsoft Office Visio and could allow remote code execution if a user opens a specially crafted Visio file. An attacker who successfully exploits this vulnerability could gain the same user rights as the current user. If the current user has administrative privileges, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. Users whose accounts are configured with fewer privileges on the system would be less impacted than users who operate with administrative privileges. The vulnerability is particularly concerning in work environments where Visio files are commonly shared and opened.
Remediation
To mitigate this vulnerability, users and administrators should:
- Apply the latest security updates from Microsoft as soon as possible
- Install the patches provided in Microsoft's security update for Office Visio
- Exercise caution when opening Visio files from untrusted sources
- Consider implementing the principle of least privilege for user accounts
- Keep antivirus and anti-malware solutions updated
- Consider using Microsoft Office's Protected View when opening files from external sources
- Implement network segmentation and restrict access to critical systems
