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.

PR.PS-05 full match
prevents

Preventing execution of unauthorized code directly blocks the malicious binaries that an untrusted search path would load.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input neutralization to block line-delimiter injection.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce safe search paths and restrict environment variables that enable the weakness.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect the weakness but does not itself implement the neutralization.

A.8.19 Installation of software on operational systems partial match
degrades

Restricting software installation reduces the chance that untrusted binaries or libraries are placed in search paths.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and sanitization that can prevent line-delimiter injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements typically include rules for neutralizing special characters such as line delimiters.

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

Secure architecture principles encourage safe data handling but do not specifically address line-delimiter neutralization.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require proper neutralization of line delimiters in input handling.
