Mitigating Controls
Mitigating Controls (NIST 800-53 r5)
Our mappings, made for this CVE.
AC-3 directly requires enforcement of authorization decisions on every access request, structurally eliminating missing authorization checks.
AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.
AC-25 requires a tamperproof, always-invoked reference monitor that ensures authorization checks cannot be omitted.
AC-6 reduces the set of actions reachable without proper authorization, limiting blast radius of missing checks.
Mitigating Controls (ISO/IEC 27001:2022 Annex A)
Our mappings, derived directly from the weakness types (CWEs) cited in the NVD entry via our CWE→ISO cross-walk — links open the control.
A.8.3's purpose is to ensure only authorized access, and its guidance directly mandates the authorization checks that CWE-862 describes as missing, so a well-implemented access restriction control fully blocks exploitation of the missing authorization weakness.
Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.
By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.
Requiring evidence of minimum security capabilities and acceptance testing ensures that missing or bypassed authorization checks are detected before the delivered software is accepted.
Mandating read-only access or proxy execution by an authorized administrator ensures every requested operation is explicitly authorized before it occurs.
Mandatory authorization checks before allowing modifications ensure that every sensitive action on source code is preceded by an explicit access-control decision.
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-862, a class-level weakness, and none of its children carries one either.
