Synopsis

The management engine on the remote host is affected by multiple vulnerabilities.

Description

The Intel Converged Security Management Engine (CSME) on the remote host is affected by multiple vulnerabilities in the Active Management Technology (AMT) feature, including the following:

- Out-of-bounds write in IPv6 subsystem for Intel(R) AMT, Intel(R) ISM versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70, 14.0.45 may allow an unauthenticated user to potentially enable escalation of privileges via network access. (CVE-2020-8752)

- Out-of-bounds read in subsystem for Intel(R) AMT versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70 and 14.0.45 may allow an unauthenticated user to potentially enable information disclosure and/or denial of service via network access. (CVE-2020-8747)

- Out-of-bounds read in subsystem for Intel(R) AMT versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70 and 14.0.45 may allow an unauthenticated user to potentially enable escalation of privilege via adjacent access. (CVE-2020-8749)

Note that due to the low-level implementation of Intel ME, Nessus may not be able to identify its version on the remote host at this time.
