"The Intel Management Engine on the remote host has Active Management Technology (AMT) enabled, and, according to its
self-reported version, is a version containing multiple vulnerabilities, including the following:

  - Insufficiently protected credentials for Intel(R) AMT and Intel(R) Standard Manageability may allow an 
    unauthenticated user to potentially enable information disclosure and escalation of privilege via network 
    access. (CVE-2022-30601)

  - Insufficiently protected credentials for Intel(R) AMT and Intel(R) Standard Manageability may allow a privileged 
    user to potentially enable information disclosure via local access. (CVE-2022-30944)

  - Improper access control in firmware for Intel(R) AMT and Intel(R) Standard Manageability may allow an 
    unauthenticated user to potentially enable escalation of privilege via physical access.(CVE-2022-28697)


Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
