Multiple Firmware Vulnerabilities in Dell Business Laptops May Result in Device Compromise

Researchers at Talos have identified a series of vulnerabilities in Dell laptops that could potentially compromise Windows systems and enable persistent access for malicious actors. The five vulnerabilities, collectively referred to as ReVault, affect Dell’s ControlVault3 Firmware and its associated Windows APIs across more than 100 models of Dell laptops, primarily within the Precision and Latitude series. These models are widely utilised in sectors that demand high security, such as cybersecurity and government environments, making the implications of these vulnerabilities particularly concerning.

Dell’s ControlVault serves as a daughter board that securely stores passwords, biometric templates, and security codes within its firmware, functioning as a Unified Security Hub. This hub connects various security-related peripherals, including NFC and smart card readers. The current versions of this product, known as ControlVault3 and ControlVault3+, are present in numerous actively supported Dell laptops, especially those designed for business use. Given the sensitive nature of the industries that employ these devices, the potential for compromise poses significant risks, particularly in environments where secure login methods are essential.
