CVE-2023-5297

Controls on authorized publication limit files and directories with nonpublic data from becoming accessible to external parties.

Controlling and documenting P2P file sharing prevents files and directories from being made accessible to external parties for unauthorized distribution.

Identifying and documenting file and directory locations allows restriction of access to external parties.

Protecting backup files ensures they are not accessible to external parties or unauthorized spheres.

Sanitizing equipment before off-site maintenance reduces the risk of files or directories containing sensitive data becoming accessible to external parties.

Policy restricts media access to authorized parties only, preventing exposure of resources to external or unauthorized actors.

Media access restrictions prevent files or directories from being accessible to external parties.

Employing and evaluating controls at documented alternate sites makes files and directories less likely to be accessible to external parties through physical or environmental weaknesses.

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

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

Explicit requirement to protect backups directly mitigates unauthorized exposure of backup files.

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

Hardened configuration baselines commonly include file-system permission settings that limit external access.

Classification helps identify which backups need stricter handling, but does not enforce storage location or access restrictions.

Access control directly limits who can reach backup files, though it does not address how backups are created or stored.

A.5.18's provisioning, revocation, review and adjustment of logical access rights (incl. before/after role changes or termination) directly stops unauthorized actors from reaching the backup file per business/policy rules; the bounded remainder is backups whose exposure is not an access-rights decision at all (e.g. the file is world-readable on a public share with no identity check).
