Summary

CVE-2024-43199 is a high-severity Incorrect Permission Assignment for Critical Resource (CWE-732) vulnerability in Nagios Ndoutils. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Abuse Elevation Control Mechanism (T1548); ranked in the top 37% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-2 (Account Management) and AC-24 (Access Control Decisions) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces the access control policy that defines permissions on resources, thereby stopping incorrect assignments from remaining exploitable.

AC-2 Account Management good match

Account management directly governs assignment and tracking of privileges so proper implementation stops the weakness from being introduced.

AC-24 Access Control Decisions good match

Requiring explicit access-control decisions ensures privileges are evaluated rather than assumed or omitted.

AC-5 Separation of Duties good match

Separation of duties constrains how privileges may be assigned, reducing the chance of overly broad actor control.

AC-6 Least Privilege good match

Directly requires assignment of only the minimum necessary permissions, preventing overly broad grants on critical resources.

AC-16 Security and Privacy Attributes partial match

Binding security attributes to subjects/objects supplies the mechanism needed to track and enforce privileges correctly.

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 full match
prevents

Directly requires defining, enforcing, and reviewing access permissions and least privilege on resources.

PR.PS-01 mostly match
prevents

Hardened baselines and configuration management explicitly include correct permission settings for critical resources.

PR.AA-01 partial match
prevents

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.

PR.PS-05 partial match
prevents

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.

PR.DS-10 none match
prevents

PR.DS-10 protects data-in-use without touching privilege assignment/tracking, so it neither prevents CWE-269 nor removes more than one narrow facet of its risk.

A.5.15 Access control mostly match
prevents

By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.

A.5.18 Access rights mostly match
prevents

Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.

A.8.2 Privileged access rights mostly match
prevents

Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.

A.8.3 Information access restriction mostly match
prevents

Requiring explicit configuration of access controls and permissions for files, applications and services counters the assignment of overly permissive default or incorrect file-system rights.

A.8.4 Access to source code mostly match
prevents

Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.

A.8.9 Configuration management mostly match
prevents

By defining and enforcing secure permission settings in configuration templates, the control reduces the likelihood that critical resources receive incorrect permission assignments.
