Local information disclosure through undisclosed Installer flaw
Published Apr 13, 2021 · Updated Aug 3, 2024
Information disclosure in Windows Installer across affected Microsoft Windows releases allows local users to read unspecified information. Microsoft has not published the vulnerable code path or the operation that exposes the information to untrusted local input. Exploitation requires low-privilege local access, and the published impact is limited to confidentiality with no integrity or availability effect.
