How to fix

Officials provided detailed steps to circumvent this vulnerability as follows:

Step 1:

Determine if you have Intel AMT, Intel supports the Intel SBA or ISM-enabled systems: . If you are sure that you do not have the above system, no further action is required.

Step 2:

Use “test guidelines” to assess whether the system has affected the firmware: . If you have a version in the Resolved Firmware column, you do not need to take further action to protect the system from this vulnerability.

Step 3:

Intel strongly recommends that you check the updated firmware with the system OEM. The firmware version that resolves the problem has a four-digit built-in version number that begins with “3” (XXXX.3XXX) Ex:

Step 4:

If you can not use the OEM firmware update, mitigation measures provided in this document are as follows:

To assist with the mitigation steps provided in this document, contact Intel Customer Support ( ); from the technical section , Select Intel Active Management Technology (Intel AMT).
