Description:

There are two ways this vulnerability may be accessed please note that Intel® Small Business Technology is not vulnerable to the first issue.

• An unprivileged network attacker could gain system privileges to provisioned Intel manageability SKUs: Intel® Active Management Technology (AMT) and Intel® Standard Manageability (ISM).
  • CVSSv3 9.8 Critical /AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
• An unprivileged local attacker could provision manageability features gaining unprivileged network or local system privileges on Intel manageability SKUs: Intel® Active Management Technology (AMT), Intel® Standard Manageability (ISM), and Intel® Small Business Technology (SBT).
  • CVSSv3 8.4 High /AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Affected products:

The issue has been observed in Intel manageability firmware versions 6.x, 7.x, 8.x 9.x, 10.x, 11.0, 11.5, and 11.6 for Intel® Active Management Technology, Intel® Small Business Technology, and Intel® Standard Manageability. Versions before 6 or after 11.6 are not impacted.

Recommendations:

Intel has released a downloadable discovery tool located at downloadcenter.intel.com, which will analyze your system for the vulnerability. IT professionals who are familiar with the configuration of their systems and networks can use this tool or can find more details below.

Step 1: Determine if you have an Intel® AMT, Intel® SBA, or Intel® ISM capable system. If you determine that you do not have an Intel® AMT, Intel® SBA, or Intel® ISM capable system then no further action is required.

Step 2: Utilize the Intel Converged Security and Management Engine Detection Tool to assess if your system has the impacted firmware. If you do have a version in the “Resolved Firmware” column no further action is required to secure your system from this vulnerability.

Step 3: Intel highly recommends checking with your system OEM for updated firmware. Firmware versions that resolve the issue have a four digit build number that starts with a “3” (X.X.XX.3XXX) Ex: 8.1.71.3608.
