CVE-2020-0535Network attack vector

Unauthenticated information disclosure via undisclosed input validation

Published Jun 15, 2020 · Updated Aug 4, 2024

Improper input validation in Intel AMT allows remote attackers to read unspecified information through network requests. Intel has not disclosed the affected interface, input field, or validation error, so the precise data-exposure mechanism remains undocumented. Network access is sufficient without authentication or user interaction, and the affected branches end at 11.8.76, 11.12.76, 11.22.76, and 12.0.63.
