CVE-2023-20235

Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments.

Access supervision ensures privileges are assigned and managed without improper escalation or retention.

Assigning group/role memberships and access authorizations (privileges) while reviewing accounts addresses improper privilege management.

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

Enforces proper privilege management by requiring all decisions through the verified reference monitor.

By mandating division of duties across roles, the control enforces proper privilege management and prevents a single entity from controlling an entire sensitive process.

Implements core proper privilege management by restricting to only required rights.

Policy requires training on privilege management and least privilege, making it harder to exploit improper privilege management weaknesses.

PR.AA-01 supplies credential/identity lifecycle support that can reduce some privilege-assignment errors but does not itself assign, modify, or check privileges, leaving most of CWE-269's risk unaddressed.

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.

PR.PS-05 can partially limit exploitability of some privilege issues via execution restrictions, but does not address the core design/implementation flaws of CWE-269 at all.

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.

Explicit restrictions on privileged access and segregation of duties limit the scope of privileges that can be assigned, reducing the chance that excessive or unnecessary privileges are granted to entities.
