Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-20 Use of External Systems
addresses: CWE-668

Controls whether organization resources are exposed to external system spheres by permitting or prohibiting their use.

AC-21 Information Sharing
addresses: CWE-668

The control ensures information is not released into a security sphere where the recipient lacks matching access authorizations.

AC-22 Publicly Accessible Content
addresses: CWE-668

The control ensures information resources are not exposed to the incorrect (public) sphere through review and authorization.

AC-23 Data Mining Protection
addresses: CWE-668

Protects against data mining that would expose resources to unauthorized spheres by enforcing detection and controls.

AC-4 Information Flow Enforcement
addresses: CWE-668

Restricts information flows to ensure resources are not exposed to incorrect or unauthorized spheres.

CA-9 Internal System Connections
addresses: CWE-668

Controlling internal connections prevents exposure of resources to unintended internal spheres.

CM-12 Information Location
addresses: CWE-668

Knowing exact processing and storage locations helps avoid exposure of resources to incorrect spheres.

MP-2 Media Access
addresses: CWE-668

The control prevents exposure of the media resource to the wrong security sphere.

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.PS-01 full match
prevents

Configuration management enforces restricted bind addresses, covering the weakness completely but only one aspect of overall hardening.

PR.AA-05 mostly match
prevents

Enforcing least-privilege authorizations directly prevents resources from being exposed outside their intended control sphere.

PR.IR-01 mostly match
prevents

Network protection controls directly prevent exposure via unrestricted binds while fixing the weakness addresses only one vector of unauthorized access.

ID.AM-03 partial match
prevents

Documenting authorized network flows informs correct bind decisions and reduces the chance of 0.0.0.0 usage.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.21 Security of network services mostly match
prevents

Security of network services includes hardening service bindings to prevent exposure on all interfaces.

A.8.27 Secure system architecture and engineering principles mostly match
prevents

Secure architecture principles discourage exposing services on all interfaces, though the control is broader than this single weakness.

A.8.20 Networks security partial match
mitigates

Network security controls directly require restricting listening interfaces to specific addresses rather than 0.0.0.0.

A.8.22 Segregation of networks partial match
mitigates

Network segregation can limit the blast radius of an unrestricted binding but does not prevent the binding itself.

A.8.28 Secure coding partial match
prevents

Secure coding guidance can catch hard-coded 0.0.0.0 bindings during development but is not the primary mitigation.

A.5.9 Inventory of information and other associated assets none match
none

Requiring owners to manage the full asset life cycle and remove assets from the inventory upon secure disposal helps prevent resources from being inadvertently exposed outside their intended security sphere.
