Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-321

Supply chain protection includes scrutiny of cryptographic implementations, reducing hard-coded keys planted by untrusted vendors.

addresses: CWE-321

Functional and assurance requirements specified in acquisition can prohibit hard-coded cryptographic keys in delivered products.

addresses: CWE-321

Proper key establishment and management processes directly preclude embedding static cryptographic keys in source code or binaries.

addresses: CWE-321

Approved PKI issuance and trust stores replace ad-hoc or hard-coded keys with properly managed, signed certificates.

addresses: CWE-321

Assessments can uncover and prevent suppliers from shipping components that contain hard-coded cryptographic keys.
