CWE-1193: Power-On of Untrusted Execution Core Before Enabling Fabric Access Control
Learn about CWE-1193 (Power-On of Untrusted Execution Core Before Enabling Fabric Access Control), its security impact, exploitation methods, and prevention guidelines.
What is Power-On of Untrusted Execution Core Before Enabling Fabric Access Control?
• Overview: This vulnerability occurs when a system initializes components with untrusted firmware before setting up necessary security controls, allowing these components potential unauthorized access to critical system resources.
• Exploitation Methods:
- Attackers can exploit this vulnerability by gaining control over untrusted components to initiate unauthorized transactions on the hardware bus.
- Common attack patterns include manipulating the system boot process or accessing sensitive memory areas before security measures are enforced.
• Security Impact:
- Direct consequences include unauthorized access to memory and manipulation of the System-on-Chip (SoC) boot firmware.
- Potential cascading effects include compromise of the entire boot process, leading to broader system vulnerabilities.
- Business impact includes data breaches, unauthorized data manipulation, and potential service disruptions.
• Prevention Guidelines:
- Ensure firmware components are verified and trusted before initialization.
- Implement security best practices like early enforcement of access controls during the boot sequence.
- Utilize recommended tools and frameworks that support secure boot processes and hardware access control mechanisms.
