Synopsis

The management engine on the remote host is affected by a remote code execution vulnerability.

Description

The Intel Management Engine on the remote host has Active Management Technology (AMT) enabled, and according to its self-reported version in the banner, it is running Intel manageability firmware version 6.x prior to 6.2.61.3535, 7.x prior to 7.1.91.3272, 8.x prior to 8.1.71.3608, 9.0.x or 9.1.x prior to 9.1.41.3024, 9.5.x prior to 9.5.61.3012, 10.0.x prior to 10.0.55.3000, 11.0.18.x prior to 11.0.18.3003, 11.0.22.x prior to 11.0.22.3001, 11.0.x prior to 11.0.25.3001, 11.6.12.x prior to 11.6.12.3202, or else 11.5.x or 11.6.x prior to 11.6.27.3264. It is, therefore, affected by a remote code execution vulnerability due to insecure read and write operations. An unauthenticated, remote attacker can exploit this to execute arbitrary code.

Note that the vulnerability is only exploitable remotely if either Active Management Technology (AMT), Intel Standard Manageability (ISM), or Small Business Technology (SBT) is enabled. However, a local attacker can still exploit the vulnerability even if these components are disabled by simply re-enabling the components.

Solution

Contact your system OEM for updated firmware per the vendor advisory.

Alternatively, apply these mitigations per the INTEL-SA-00075 mitigation guide :

- Unprovision Intel manageability SKU clients.
- Disable or remove the Local Manageability Service (LMS).
- Configure local manageability configuration restrictions.
