If this line is True, the required hardware features are present. The device OEM is responsible for providing the updated BIOS/firmware that contains the microcode provided by CPU manufacturers. This line tells you if hardware features are present to support the branch target injection mitigation. Hardware support for branch target injection mitigation is present This section provides system status for variant 2, CVE-2017-5715, branch target injection. This appears because PowerShell prints the object that is returned by a function. The final output grid maps to the output of the preceding lines. SSBDWindowsSupportEnabledSystemWide: False

Speculation control settings for CVE-2017-5715 Enabled protections appear in the output as “True.” The output of this PowerShell script will resemble the following. Start PowerShell, and then (using the example above) copy and run the following commands: Run the PowerShell module to verify that protections are enabled
#The used vulnerable zip install
Install the PowerShell module from TechNet ScriptCenterĭownload SpeculationControl.zip to a local folder.Įxtract the contents to a local folder, for example C:\ADV180002

This topic provides details about the PowerShell script that helps determine the state of the mitigations for the listed CVEs that require additional registry settings and, in some cases, firmware updates. Protection for CVE-2017-5753 (bounds check) does not require additional registry settings or firmware updates.
