Intel Management Engine Insecure Read / Write Operations RCE (INTEL-SA-00075)
Critical Nessus Plugin ID 97997
SynopsisThe management engine on the remote host is affected by a remote code execution vulnerability.
DescriptionThe Intel Management Engine on the remote host has Active Management Technology (AMT) enabled and is running Intel manageability firmware version 6.x prior to 184.108.40.20635, 7.x prior to 220.127.116.1172, 8.x prior to 18.104.22.16808, 9.0.x or 9.1.x prior to 22.214.171.12424, 9.5.x prior to 126.96.36.19912, 10.0.x prior to 10.0.55.3000, 11.0.18.x prior to 188.8.131.5203, 11.0.22.x prior to 184.108.40.20601, 11.0.x prior to 220.127.116.1101, 11.6.12.x prior to 18.104.22.16802, or else 11.5.x or 11.6.x prior to 22.214.171.12464. 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.
Also, 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.
SolutionContact 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.
