Local privilege escalation via malformed TSF messages
Published Jun 9, 2020 · Updated Aug 4, 2024
Elevation of privilege in Microsoft Windows TSF allows local users to gain elevated privileges through crafted TSF client messages. The TSF server improperly handles messages received from TSF clients, but Microsoft has not disclosed the specific message field or validation error involved. Exploitation requires local execution and user interaction, after which local users can affect protected data and service availability with elevated privileges.
