To exploit this, the attacker needs to remove the tamper label and all fixing screws from the device without damaging it. This is called an F14 attack.\n\n## Affected\n\n- `nshield_5c_firmware < 13.6.12`\n- `nshield_5c_firmware >= 13.7, < 13.9.0`\n- `nshield_hsmi_firmware < 13.6.12`\n- `nshield_hsmi_firmware >= 13.7, < 13.9.0`\n- `nshield_connect_xc_base_firmware < 13.6.12`\n- `nshield_connect_xc_base_firmware >= 13.7, < 13.9.0`\n- `nshield_connect_xc_mid_firmware < 13.6.12`\n- `nshield_connect_xc_mid_firmware >= 13.7, < 13.9.0`\n- `nshield_connect_xc_high_firmware < 13.6.12`\n- `nshield_connect_xc_high_firmware >= 13.7, < 13.9.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `nshield_5c_firmware 13.9.0`\n- `nshield_hsmi_firmware 13.9.0`\n- `nshield_connect_xc_base_firmware 13.9.0`\n- `nshield_connect_xc_mid_firmware 13.9.0`\n- `nshield_connect_xc_high_firmware 13.9.0`","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":50.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
