Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

SI-10 Information Input Validation good match

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

AC-3 Access Enforcement partial match

Enforces authorization checks on the code or classes ultimately invoked, blocking unauthorized selections even if reflection is used.

AC-6 Least Privilege partial match

Least privilege limits the damage an injected code fragment can perform once executed.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

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 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover unsafe reflection during code review or scanning.

PR.PS-05 partial match
prevents

Preventing execution of unauthorized code can block exploitation of unsafe reflection at runtime.

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

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 directly forbid unsafe reflection and require whitelisting or static alternatives.

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

Security testing can detect and block unsafe reflection patterns before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and design reviews that reduce unsafe reflection risks.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly prohibit or constrain reflection based on untrusted input.

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

Secure architecture principles discourage dynamic class loading from external data sources.

A.8.3 Information access restriction none match
none

Access restrictions limit who can supply the malicious input but do not address the reflection flaw itself.
