David Bombal sits down with Philippe Laulheret of Cisco Talos at Black Hat to unpack new vulnerabilities in Dell’s ControlVault security board (the module behind fingerprint/smart-card/NFC on many Latitude/Precision laptops). Laulheret chains two bugs to get code execution, leaks device-unique AES/HMAC keys, and modifies firmware for persistence. He then backdoors a function so requesting object “1337” delivers a payload that abuses the Windows Biometric Framework (Broadcom DLL) to spawn a SYSTEM reverse shell. Demos: onion/plastic-finger unlock and a physical USB ribbon-cable attack path.
