From the web page screenshot, the following key information about the vulnerability can be extracted: Vulnerability Title: BIOS code logic error Vulnerable System: Any workstation running the ACPI 1.6 BIOS implementation, specifically on the Toshiba Satellite Pro A60 with ACPI BIOS version 1.60. Vulnerability Detail: There is a programming error in the BIOS when the Master Boot Record (MBR) is searched for the bootable disk partition. The active partition in MBR partition table only tests the first slot. If the active partition is not in the first slot, the BIOS ignores the remaining slots and fails to start the Operating System. Impact: The system will not boot. Standard analysis tools will not identify the contents of the MBR partition as invalid, leading to a denial of service. Exploit: The BIOS code can be exploited by configuring the bootable partition below the first slot in the MBR partition table. The system becomes unable to reboot until the MBR is corrected or reconfigured. Vendor Response and Fix: Toshiba did not recognize the fault. The BIOS code must be corrected by the manufacturer, or a monitoring device should be installed to detect and correct any re-configuration that would exploit the vulnerability. Validating and correcting the MBR at system shutdown is a minimum requirement.
