Mitigating Controls

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.

addresses: CWE-923

Authorizing wireless access restricts the wireless communication channel to only intended endpoints.

addresses: CWE-923

Approving specific exchanges and documenting interface characteristics restricts communication channels to only intended endpoints and systems.

addresses: CWE-923

Limits physical connectivity to transmission channels, supporting restriction of communication paths to only intended endpoints.

addresses: CWE-923

Requiring providers to meet communication-channel restrictions and monitoring adherence reduces improper restriction of channels to intended endpoints.

addresses: CWE-923

Mandates restriction of the channel for authentication to only the intended trusted endpoints, blocking unauthorized communication paths.

addresses: CWE-923

Explicit control of VoIP traffic forces organizations to restrict communication channels to only intended endpoints and protocols.

addresses: CWE-923

Explicit internal/external separation restricts name-resolution channels to their intended communication endpoints.

addresses: CWE-923

Enforces that the wireless communication channel is usable only by intended endpoints, addressing improper channel restriction.

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.

degrades

Network security controls directly enforce endpoint validation and channel restrictions.

blocks

A.8.21 mandates identifying/implementing network service security features (authentication, encryption, connection controls, authorization, monitoring, allowed endpoints via rules) and ensuring providers do so, which stops most improper-restriction cases from being exploitable; the bounded remainder is product-level endpoint validation logic (e.g. cert pinning, strict hostname checks) that lives in code rather than in service configuration or provider agreement.

blocks

Cryptography can protect channels but does not guarantee correct endpoint identity without additional controls.

blocks

Application security requirements may specify endpoint validation but do not implement it.

blocks

A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, assume-breach, never-trust/always-verify, end-to-end encryption, dynamic access control) plus design reviews that can stop many channel-misrouting flaws at source, but leaves a bounded remainder (e.g. flawed protocol selection or implementation bugs in the chosen channel that still reach the wrong endpoint).

prevents

Secure coding practices can implement endpoint checks but the control itself is process-oriented.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-923, a class-level weakness. Rules are authored against its narrower children: CWE-419.
