Security researchers have disclosed an unpatched weakness in Microsoft Windows Platform Binary Table (WPBT) affecting all Windows-based devices since Windows 8 that could be potentially exploited to install a rootkit and compromise the integrity of devices.

“These flaws make every Windows system vulnerable to easily-crafted attacks that install fraudulent vendor-specific tables,” according to security researchers. “These tables can be exploited by attackers with direct physical access, with remote access, or through manufacturer supply chains. More importantly, these motherboard-level flaws can obviate initiatives like Secured-core because of the ubiquitous usage of ACPI [Advanced Configuration and Power Interface] and WPBT.”

In response to the findings, Microsoft has recommended using a Windows Defender Application Control (WDAC) policy to tightly restrict what binaries can be permitted to run on the devices.
