Insecure default initialization of resource in Intel(R) Boot Guard in Intel(R) CSME versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70, 13.0.40, 13.30.10, 14.0.45 and 14.5.25, Intel(R) TXE versions before 3.1.80 and 4.0.30, Intel(R) SPS versions before E5_04.01.04.400, E3_04.01.04.200, SoC-X_04.00.04.200 and SoC-A_04.00.04.300 may allow an unauthenticated user to potentially enable escalation of privileges via physical access.

Weakness

The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.

Extended Description

Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
