CVE-2025-59704 Entrust nShield HSM BIOS物理访问未授权漏洞

# CVE-2025-59704 PoC - Physical Access to Entrust nShield HSM BIOS # This PoC demonstrates the physical access requirement for exploiting this vulnerability print("CVE-2025-59704 Proof of Concept") print("=" * 50) print("Target: Entrust nShield Connect XC, nShield 5c, nShield HSMi") print("Affected Versions: <= 13.6.11, 13.7") print() poc_steps = """ Physical Exploitation Steps: 1. Physical Access Required - Gain physical access to the nShield HSM device - Locate the device console port or direct interface 2. Reboot the Device - Power cycle the nShield HSM device - Or press the physical reset button if available 3. Enter BIOS Setup - During boot, press the appropriate BIOS key (typically DEL, F2, or ESC) - The key varies by hardware platform but no password is required 4. Unauthorized BIOS Access - Access BIOS configuration without authentication - View and modify all BIOS settings 5. Exploitation Options: a) Modify boot order to boot from external USB/CD b) Disable secure boot c) Extract firmware for reverse engineering d) Modify security configurations e) Reset administrator credentials 6. Persistence - Flash malicious firmware if desired - Configure backdoor access - Extract stored encryption keys Note: This is a physical security vulnerability. Remote exploitation is NOT possible. The only mitigation is physical security controls and firmware updates from Entrust.
