Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly requires enforcement of authorization decisions on every access request, structurally eliminating missing authorization checks.

AC-24 Access Control Decisions good match

AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.

AC-25 Reference Monitor good match

AC-25 requires a tamperproof, always-invoked reference monitor that ensures authorization checks cannot be omitted.

CM-6 Configuration Settings good match

Requires secure baseline settings that disable directory listing on servers and file shares.

CM-7 Least Functionality good match

Restricts unnecessary server features such as automatic directory indexing.

AC-4 Information Flow Enforcement partial match

Controls information flows so directory contents are not disclosed to unauthorized recipients.

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.AA-05 full match
prevents

Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing authorization checks.

PR.PS-01 mostly match
prevents

Hardened baselines and config management directly disable directory listing by default.

ID.AM-08 partial match
prevents

Lifecycle management includes applying secure configurations that would prevent directory exposure.

ID.RA-01 partial match
prevents

Vulnerability scanning can discover exposed directories so they can be remediated.

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.8.3 Information access restriction full match
prevents

Information access restriction directly prevents directory listings by enforcing need-to-know access controls on web resources.

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

Security testing in development and acceptance can detect and require remediation of exposed directory listings.

A.5.15 Access control partial match
prevents

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

A.5.18 Access rights partial match
prevents

Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.

A.5.3 Segregation of duties partial match
mitigates

Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.

A.5.35 Independent review of information security partial match
finds

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

Hardening callouts derived

Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against. Derived via CVE→CWE over `controls_xwalks` (authoritative rows only; rows rated `none` are excluded).
