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.
Supply chain protection includes scrutiny of cryptographic implementations, reducing hard-coded keys planted by untrusted vendors.
Functional and assurance requirements specified in acquisition can prohibit hard-coded cryptographic keys in delivered products.
Proper key establishment and management processes directly preclude embedding static cryptographic keys in source code or binaries.
Approved PKI issuance and trust stores replace ad-hoc or hard-coded keys with properly managed, signed certificates.
Assessments can uncover and prevent suppliers from shipping components that contain hard-coded cryptographic keys.
