Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly requires neutralizing untrusted data before it is used to build XPath queries.

A.8.28 Secure coding mostly match
prevents

Secure coding standards require proper neutralization of untrusted input in XPath expressions.

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

Security testing in development catches XPath injection vulnerabilities before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and query parameterization that directly prevent XPath injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for defenses against injection flaws including XPath injection.

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

Secure architecture principles reduce the likelihood of unsafe dynamic query construction.

A.8.8 Management of technical vulnerabilities partial match
finds

Vulnerability management processes identify and remediate XPath injection flaws discovered post-deployment.
