Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly enforces authorization checks on access to files and directories, stopping unauthorized external exposure.

AC-6 Least Privilege good match

AC-6 limits granted privileges, reducing the chance that files or directories become reachable by external parties.

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.

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.AA-05 mostly match
prevents

Enforcing least-privilege permissions and authorization policies directly prevents unauthorized file/directory exposure.

PR.IR-01 mostly match
prevents

Logical segmentation and access protections stop external parties from reaching files that should remain internal.

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.

PR.DS-01 partial match
prevents

Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.

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.5.11 Return of assets partial match
mitigates

By tracing and retrieving all copies of information stored on endpoint and portable devices, the control reduces the likelihood that files remain accessible outside the organization’s security perimeter.

A.5.12 Classification of information partial match
mitigates

Labeling information according to its sensitivity and specifying corresponding protection measures makes it less probable that files or directories containing sensitive content will be left accessible to external parties.

A.5.9 Inventory of information and other associated assets partial match
mitigates

Including asset location and ownership in the inventory, combined with secure disposal procedures, decreases the chance that files or directories remain accessible to external parties after they should have been removed or restricted.

A.7.1 Physical security perimeters partial match
mitigates

Solid perimeters and locked external access points stop files, devices, or directories containing sensitive data from being reachable by external parties who could otherwise walk in or break in.

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).

Oracle Linux 8 (2 rules)
  • V-248579 OL 8 must restrict access to the kernel message buffer. prevents CWE-552
  • V-248597 There must be no "shosts.equiv" files on the OL 8 operating system. prevents CWE-552
