Documenting requirements and authorizing remote access ensures proper protection of alternate paths.
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.
Access control policy directly requires protection of all entry points to restricted functionality.
Managing access rights must cover every alternate path that could bypass intended restrictions.
Privileged access rights must be enforced on every possible route to privileged functions.
Secure development lifecycle includes design reviews that should identify and close alternate paths.
A.8.27 mandates security-by-design, defence-in-depth, least privilege, default-deny, fail-securely, distrust-external-input, assume-breach and zero-trust principles plus explicit design reviews against known attack patterns; these directly close most alternate-path bypasses (e.g. by enforcing consistent authorization on every path), leaving only the bounded remainder of paths that arise from incomplete requirements or post-design code changes.
Secure coding practices reduce the likelihood of unprotected alternate paths in source code.
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-424, a class-level weakness, and none of its children carries one either.
