A newly discovered security vulnerability, tracked as CVE-2024-21302 and CVE-2024-38202, allows attackers to downgrade systems to vulnerable states undetected. This vulnerability affects Windows 10, Windows 11, Windows Server 2016, and higher systems, enabling attackers to replace current system files with outdated versions. Microsoft is developing a security update to address this issue and has released mitigation strategies for supported Windows versions. Administrators can deploy a Microsoft-signed revocation policy to prevent loading vulnerable VBS system files. Home users are advised against manually installing the policy and should wait for an automatic fix.
