Mitigating Controls

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.

ID.RA-01 partial match
blocks

Vulnerability identification processes will discover path traversal weaknesses during code or configuration review.

PR.AA-05 partial match
blocks

Least-privilege file permissions and access enforcement can limit the damage from a successful traversal.

PR.PS-06 partial match
blocks

Secure SDLC practices directly require input validation and path sanitization that prevent directory traversal flaws.

A.8.19 Installation of software on operational systems partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure development lifecycle mandates input validation and path sanitization that directly prevents directory traversal.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against SQLi or buffer overflows) be identified and specified during development or acquisition; it does not itself neutralize path traversal sequences or stop exploitation of CWE-27.

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

Secure architecture principles discourage unsafe path construction but do not prescribe the specific coding fix.

A.8.28 Secure coding partial match
prevents

Secure coding standards require neutralizing '../' sequences and using safe file APIs, eliminating this exact weakness.

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

Security testing in development catches path-traversal flaws before release but does not itself implement the control.
