Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Mandates use of cryptography to protect sensitive information, preventing its unencrypted storage in environment variables.

SC-28 Protection of Information at Rest good match

Requires confidentiality protection (typically encryption) for information at rest, directly stopping cleartext storage of sensitive data in environment variables.

IA-12 Identity Proofing good match

Identity proofing at appropriate assurance levels ensures forgotten-password recovery cannot succeed without strong verification of the user.

IA-5 Authenticator Management good match

Authenticator management requires secure distribution, reset, and verification procedures that directly address weak password recovery flows.

Mitigating Controls (NIST CSF 2.0) AI

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

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

PR.AA-01 mostly match
prevents

Credential lifecycle management directly includes password reset/recovery flows.

PR.AA-02 mostly match
prevents

Identity proofing is the core control that prevents weak or bypassed recovery mechanisms.

PR.AA-03 partial match
prevents

Authentication policy covers strength/MFA but does not address recovery path weaknesses.

PR.PS-01 partial match
prevents

Hardened configuration baselines and management practices reduce the chance of secrets being left in environment variables.

PR.PS-06 partial match
prevents

Secure SDLC reduces implementation flaws but is not specific to password-recovery design.

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.8.24 Use of cryptography mostly match
prevents

Cryptography control directly addresses the lack of encryption for sensitive data stored in environment variables.

A.5.12 Classification of information partial match
mitigates

Classification drives decisions on what must be protected, indirectly discouraging cleartext storage of sensitive data.

A.5.17 Authentication information partial match
mitigates

Authentication secrets are a common type of sensitive information; the control requires protecting them, which this weakness violates.

A.7.14 Secure disposal or re-use of equipment partial match
mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

A.7.9 Security of assets off-premises partial match
mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

A.8.10 Information deletion partial match
degrades

Requires secure deletion of sensitive information, which would prevent leaving it in environment variables.
