QID 375942: Microsoft Windows Platform Binary Table (WPBT) Remote Code Execution (RCE) Vulnerability

WPBT is a feature that allows OEMs to modify the host operating system during boot to include vendor-specific drivers, applications, and content.
Microsoft's WPBT allow an attacker to run malicious code with kernel privileges when a device boots up. QID Detection Login (Authenticated): Looks for the %systemdrive%\Windows\system32\wpbbin.exe file.

Successful exploitation of this flaw may allow an attacker to execute arbitrary code on the target system.

CVSS V3 rated as Critical - 9.8 severity.

CVSS V2 rated as Critical - 10 severity.

Solution

Microsoft recommends customers use Windows Defender Application Control (WDAC) to limit what is allowed to run on their devices. WDAC policy is also enforced for binaries included in the WPBT and should mitigate this issue. We recommend customers implement a WDAC policy that is as restrictive as practical for their environment.
