Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover missing neutralization of template directives.

Input validation rejects or sanitizes untrusted data before it reaches the template engine, stopping injection of special syntax.

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

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

Security engineering principles require use of safe templating APIs and proper escaping of external input.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper input neutralization in template engines to prevent injection.

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.

finds

Security testing can detect template-injection flaws but does not itself implement neutralization controls.

prevents

Secure development life cycle mandates input validation and sanitization that directly prevents template-injection weaknesses.

prevents

Application security requirements explicitly call for neutralizing special elements in template engines.

prevents

Secure architecture principles reduce the likelihood of unsafe template processing but do not prescribe specific neutralization techniques.

prevents

Secure coding standards require proper escaping or sandboxing of template directives, directly mitigating CWE-1336.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
