Local information disclosure via undisclosed filter-driver flaw
Published Jan 12, 2021 · Updated Oct 8, 2024
Information disclosure in Microsoft Windows 10 and Windows Server versions 2004 and 20H2 allows local users to read unspecified information. Microsoft has not published the affected Projected File System filter driver's faulty operation or the input that reaches it. Exploitation requires local low-privileged access, and the published assessment limits the consequence to disclosure without modification or service interruption.
