CVE-2023-22858

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

Enumerating systems surfaces externally reachable resources that would otherwise remain unmonitored and accessible.

Prevents public exposure of files or directories that should not be reachable by unauthenticated parties.

Decoy files and directories detect external access attempts and deflect attackers away from actual accessible resources.

Requiring an access control policy ensures authorization checks are defined and applied for critical functions.

Reviews of access controls detect missing authorization checks on critical functions or resources.

Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.

Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.

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

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

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.

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.

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.

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.

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.
