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.
Mandates provision of authenticity and integrity artifacts that enable verification of name/address resolution data.
Requires explicit verification of data authenticity from authoritative sources, preventing acceptance of unauthenticated resolution responses.
Requires unique identification of the service before communications, addressing failures to validate the origin of the interaction.
Directly requires independent verification of matching output before adverse decisions, mitigating insufficient authenticity checks on data from external sources.
Trusted path establishment enforces validation that the communication originates from and reaches only the intended trusted system components.
Use of approved PKI certificates provides verifiable data authenticity and origin for communications and artifacts.
Mandates origin validation so that only legitimate endpoints can continue the authenticated session.
Control requires verification of data authenticity/integrity (e.g., checksums) after aggregation/packing, directly reducing exploitation of insufficient verification before transmission.
