Windows LSA Service LsapGetClientInfo Impersonation Level Check Privilege Escalation

Windows LSA Service LsapGetClientInfo Impersonation Level Check Privilege Escalation
Posted Jul 15, 2022
Authored by James Forshaw, Google Security Research

On Microsoft Windows, the LsapGetClientInfo API in LSASRV will fallback and directly capture a caller's impersonation token if it fails to impersonate, leading to elevation of privilege if the impersonation level is not checked.
