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.

SC-18 Mobile Code
addresses: CWE-913

Requiring explicit authorization and ongoing control of mobile code implements proper management of dynamically loaded code resources.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 partial match
blocks

Secure SDLC practices directly prevent dynamic variable control flaws via coding standards, reviews, and testing.

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.5.13 Labelling of information partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure development lifecycle requires input validation and variable handling rules that reduce dynamic-variable misuse.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against injections or input controls) be identified and specified during development or acquisition; it does not itself enforce, implement or assure those requirements against dynamically-identified variable misuse, so the weakness remains exploitable.

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

Secure architecture principles discourage unsafe dynamic variable access patterns.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit uncontrolled dynamic variable access.

A.8.29 Security testing in development and acceptance partial match
finds

Security testing can detect and prevent dynamic-variable weaknesses before release.

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-913, a class-level weakness, and none of its children carries one either.
