Local privilege escalation
Published May 11, 2021 · Updated Aug 3, 2024
Elevation of privilege in Microsoft Windows Container Manager Service allows local users with low privileges to gain elevated privileges on the host. Microsoft's public advisory identifies the affected service but does not disclose the flawed function, data flow, or operation on attacker-controlled input. Exploitation requires existing local privileges and no user interaction; success grants privileges beyond those of the attacker's existing account.
