Installer content spoofing through undisclosed mechanism
Published Apr 13, 2021 · Updated Aug 3, 2024
Spoofing in Windows Installer on affected Microsoft Windows releases allows local users to alter installation content through local access. Microsoft has not published the affected code path or the incorrect operation performed on untrusted installer data. Exploitation requires local access but no prior privileges, and the documented consequence is loss of integrity without disclosure or service interruption.
