Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7, allow a Physically Proximate Attacker to access the internal components of the appliance, without leaving tamper evidence. 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.

Lifecycle Timeline
2Executive ViewAI
Entrust HSM appliances (nShield Connect XC, nShield 5c, nShield HSMi up to versions 13.6.11/13.7) contain a critical physical tampering vulnerability allowing attackers with direct device access to extract cryptographic keys without detection. Organizations using these devices for key management in payment systems, PKI, or regulatory-sensitive environments face potential compromise of their entire cryptographic infrastructure.
Implement strict physical security controls: restrict device access to authorized personnel only via locked rooms/cages with access logging and video surveillance; establish tamper-evident seals and regular physical inspections with documented audit trails; consider air-gapped deployment or network segmentation to limit cryptographic key usage if devices are compromised; implement cryptographic key rotation policies and monitor for unauthorized key access or use; for critical applications, evaluate hardware security module alternatives pending patch availability; ensure all physical access attempts trigger alerts and investigation protocols.
