CVE-2022-29893Network attack vector

Authenticated privilege escalation via undisclosed authentication flaw

Published Nov 11, 2022 · Updated Feb 5, 2025

Improper authentication in Intel AMT firmware allows remote authenticated users to escalate privileges through network access. Intel has not published the affected authentication routine or the incorrect operation that accepts a privileged request. Valid AMT credentials and network access are required; successful exploitation grants elevated control that can disclose and modify data, with no service interruption reported.
