UEFI (Unified Extensible Firmware Interface) software is an interface between a device’s firmware and the operating system, which handles the booting process, system diagnostics, and repair functions.
Security researchers have discovered major flaws with the UEFI which can allow privileged access, the potential for persistent malware, and allows a threat actor to embedding malicious code in the BIOS.
An attacker with privileged user access to the targeted system can exploit the vulnerabilities to install highly persistent malware. The threat actor can bypass virtualization-based security, Secure Boot, and endpoint security solutions.
- Potential Impact: Privilege escalation, denial of service, information disclosure
- Specific Technology Affected: UEFI firmware from InsydeH2O.
- Severity: High
- Scope of Impact: Industry-wide
