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.

A.5.20 Addressing information security within supplier agreements partial match
removes
A.5.24 Information security incident management planning and preparation partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure development lifecycle includes code review and testing that can catch incorrect comparison logic.

A.8.26 Application security requirements partial match
blocks

Application security requirements can mandate correct comparison logic for security decisions.

A.8.27 Secure system architecture and engineering principles partial match
blocks

Secure architecture principles can require robust comparison mechanisms for access decisions.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address avoiding incorrect comparison operators and logic.

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-697, a pillar-level weakness, and none of its children carries one either.
