AI-suggested

1. Upgrade affected systems: The most effective mitigation is to update Windows 10 Version 1507 systems to a supported, patched version of Windows 10 or later where this vulnerability is resolved. 2. Restrict local user privileges: Limit the number of users with local access and ensure users operate with the least privilege necessary to reduce exploitation opportunities. 3. Implement application whitelisting and endpoint protection: Use security solutions that can detect and block suspicious attempts to exploit privilege escalation vulnerabilities. 4. Monitor file system changes and symbolic link creations: Deploy monitoring tools to detect unusual link or junction point creations that could indicate exploitation attempts. 5. Harden Windows Installer usage: Restrict or audit the use of Windows Installer in sensitive environments to prevent unauthorized package installations or manipulations. 6. Employ network segmentation: Isolate legacy systems to limit potential lateral movement if exploitation occurs. 7. Prepare incident response plans: Ensure readiness to respond to privilege escalation incidents with appropriate forensic and remediation capabilities. 8. Regularly review and audit local accounts and permissions to detect and remove unnecessary privileges.

Description

Improper link resolution before file access ('link following') in Windows Installer allows an authorized attacker to elevate privileges locally.
