CVE-2020-0531Network attack vector

Authenticated information disclosure via undisclosed input validation

Published Jun 15, 2020 · Updated Aug 4, 2024

Improper input validation in Intel AMT before 11.8.77, 11.12.77, 11.22.77, and 12.0.64 allows remote authenticated users to read data. Intel has not published the affected AMT component, input type, validation error, or request path. Network access and valid AMT credentials are required; successful exploitation reads information without changing data or interrupting service.
