CVE-2020-1199

Local privilege escalation via memory object mishandling

Published Jun 9, 2020 · Updated Aug 4, 2024

Elevation of privilege in Microsoft Windows Feedback Hub allows local users with low privileges to gain elevated rights through local access. Microsoft has disclosed only that Feedback Hub improperly handles objects in memory; no public advisory identifies the object type, code locus, or faulty memory operation. Exploitation requires an existing local low-privilege account and can cross a privilege boundary, while remote access and user interaction are not reported attack paths.
