Administrator-to-BIOS arbitrary code execution

Published Mar 16, 2023 · Updated Feb 26, 2025

Improper input validation in Dell Embedded Box PC 3000 System BIOS allows local users with administrator privileges to execute arbitrary code. Dell has not disclosed the affected BIOS component, the accepted input, or the validation operation that mishandles it. Exploitation requires local authenticated administrator access and high complexity, and successful exploitation crosses into the BIOS execution context.
