Mitigating Controls
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.
Secure development lifecycle mandates server-side validation and prevents reliance on client enforcement.
Application security requirements explicitly call for server-side enforcement of security mechanisms.
Secure architecture principles discourage client-side trust but do not directly address this weakness.
Secure coding standards require server-side checks and reject client-only enforcement.
Security testing can detect client-side enforcement but is not the primary mitigation.
Information access restriction is undermined when the client is trusted to enforce it.
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-602, a class-level weakness, and none of its children carries one either.
