Chapter 1: Overview of the Vulnerability

Recent findings have revealed that numerous MSI motherboards are compromised due to a significant security lapse. Polish security expert Dawid Potocki unearthed this flaw while configuring Secure Boot on his new desktop setup. Secure Boot is a vital feature designed to verify that UEFI drivers and operating system boot loaders possess a trusted digital signature before they are permitted to run.

Section 1.1: Details of the Issue

Potocki discovered that MSI had modified the default Secure Boot configurations in their firmware. Specifically, an option referred to as "Image Execution Policy" was set to "Always Execute." This alarming setting allows the motherboard to operate even if security breaches are identified and the operating system is deemed untrusted.

Subsection 1.1.1: Impact on Users

End users remain largely unaware of their system's vulnerability unless they proactively inspect their Secure Boot settings. Potocki identified that over 290 MSI motherboard models are susceptible to this flaw, with the comprehensive list accessible on GitHub.

Chapter 2: Manufacturer Response

Despite the gravity of this issue, it appears that MSI has not prioritized addressing the vulnerability. Potocki noted, “If you are curious, yes, I have tried contacting MSI about this issue, but they ignored my emails and other forms of communication I have tried.”
