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 full match
prevents

Secure SDLC practices explicitly include controls that prevent improper handling of dynamic code resources.

PR.PS-05 mostly match
prevents

Blocking unauthorized code execution directly limits the ability to abuse dynamically-managed resources.

DE.CM-09 partial match
prevents

Runtime-environment monitoring can detect exploitation of the weakness but does not prevent it.

ID.RA-01 partial match
prevents

Vulnerability identification can surface instances of CWE-913 but does not mitigate the root weakness.

PR.PS-01 partial match
prevents

Hardened configuration baselines can restrict dynamic code execution and variable access at runtime.

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.8.28 Secure coding mostly match
prevents

Secure coding standards explicitly forbid unsafe dynamic attribute assignment and require property allow-lists.

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

Security testing can detect mass-assignment flaws but does not itself prevent them at runtime.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle requires input validation and object-property whitelisting that directly mitigates mass-assignment risks.

A.8.26 Application security requirements partial match
prevents

Application security requirements include explicit rules for allowable object attributes and safe deserialization.

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

Secure architecture principles mandate strict control over dynamic object modification and attribute binding.

A.8.3 Information access restriction partial match
prevents

Information access restriction limits who can modify objects but does not address which attributes may be changed.

Hardening callouts derived

Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against. Derived via CVE→CWE over `controls_xwalks` (authoritative rows only; rows rated `none` are excluded).

Windows 10 (1 rule)
  • V-220726 Data Execution Prevention (DEP) must be configured to at least OptOut. prevents CWE-913
Windows 11 (1 rule)
  • V-253283 Data Execution Prevention (DEP) must be configured to at least OptOut. prevents CWE-913
