Likely Mitigating Controls AI

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.

SC-20 Secure Name/Address Resolution Service (Authoritative Source)
addresses: CWE-345 CWE-346

Mandates provision of authenticity and integrity artifacts that enable verification of name/address resolution data.

SC-21 Secure Name/Address Resolution Service (Recursive or Caching Resolver)
addresses: CWE-345 CWE-346

Requires explicit verification of data authenticity from authoritative sources, preventing acceptance of unauthenticated resolution responses.

IA-9 Service Identification and Authentication
addresses: CWE-346

Requires unique identification of the service before communications, addressing failures to validate the origin of the interaction.

PT-8 Computer Matching Requirements
addresses: CWE-345

Directly requires independent verification of matching output before adverse decisions, mitigating insufficient authenticity checks on data from external sources.

SC-11 Trusted Path
addresses: CWE-346

Trusted path establishment enforces validation that the communication originates from and reaches only the intended trusted system components.

SC-17 Public Key Infrastructure Certificates
addresses: CWE-345

Use of approved PKI certificates provides verifiable data authenticity and origin for communications and artifacts.

SC-23 Session Authenticity
addresses: CWE-346

Mandates origin validation so that only legitimate endpoints can continue the authenticated session.

SC-33 Transmission Preparation Integrity
addresses: CWE-345

Control requires verification of data authenticity/integrity (e.g., checksums) after aggregation/packing, directly reducing exploitation of insufficient verification before transmission.

PR.AA-03 mostly match
prevents

Authentication directly verifies the source of users/services/hardware, mitigating origin validation failures.

PR.AA-04 mostly match
prevents

Verifying identity assertions enforces origin validation for conveyed claims.

RC.RP-05 mostly match
degrades

CWE-345 directly impairs RC.RP-05's verification of restored-asset integrity/authenticity, largely defeating the outcome while still leaving other restoration-confirmation steps partially viable.

ID.AM-03 partial match
prevents

Documenting authorized flows supports origin validation by defining expected sources.

PR.IR-01 partial match
prevents

Protecting networks from unauthorized access requires origin checks on communication sources.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect missing or weak data authenticity verification.

A.8.20 Networks security partial match
mitigates

Network controls can enforce authenticated channels, reducing risk of accepting unauthentic data.

A.8.21 Security of network services partial match
mitigates

Secure network services often include authenticity checks for data exchanged over those services.

A.8.22 Segregation of networks partial match
mitigates

Network segregation reduces exposure but does not directly validate origins.

A.8.24 Use of cryptography partial match
prevents

Cryptographic mechanisms directly verify data origin and integrity, preventing acceptance of unauthentic data.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC incorporates authenticity verification requirements throughout development.
