Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.

AC-6 Least Privilege good match

Requires least-privilege defaults so that installed files are not world-writable by default.

CM-6 Configuration Settings good match

Requires documented, restrictive configuration settings that cover file and directory permissions.

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover unquoted search paths through static analysis or dynamic test cases.

CM-5 Access Restrictions for Change partial match

Enforces access restrictions on changes, including permission settings applied during installation or configuration.

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

Documented development standards and tools can mandate proper quoting and escaping of path elements.

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-01 full match
prevents

Hardened baselines and configuration management explicitly require correct default file permissions.

PR.AA-05 mostly match
prevents

Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent path-handling flaws such as unquoted elements during development.

ID.AM-08 partial match
prevents

Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.

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 in development can detect unquoted search-path issues before deployment.

A.8.9 Configuration management mostly match
prevents

Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.

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

Enforcing controlled software installation can prevent unquoted search-path elements in executables and scripts.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle practices include input validation and path handling that reduce unquoted search-path weaknesses.

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

Secure system architecture and engineering principles require safe path construction and quoting conventions.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly mandate quoting search paths and avoiding unsafe path construction.

Hardening callouts derived
