Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

CA-2 Control Assessments
addresses: CWE-358

Assessments identify and document improperly implemented security checks, allowing fixes that reduce exploitation of flawed checks.

PR.PS-06 partial match
blocks

Secure SDLC practices directly require correct implementation of standardized security checks and algorithms.

A.5.6 Contact with special interest groups partial match
removes
A.8.19 Installation of software on operational systems partial match
removes
A.8.24 Use of cryptography partial match
blocks

Use of cryptography control depends on correct implementation of standardized cryptographic checks.

A.8.25 Secure development life cycle partial match
blocks

A.8.25 mandates security requirements, checkpoints, secure coding, testing (incl. code scans/pen tests) and developer capability in the SDLC, which reaches a minority slice of CWE-358 (incorrect implementation of a standardized security check) but leaves most instances (e.g. flawed protocol logic, spec misinterpretation, or non-coded design errors) unaddressed.

A.8.26 Application security requirements partial match
blocks

Application security requirements explicitly call for correct implementation of standardized security mechanisms.

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

A.8.27 mandates applying security-by-design principles (defense-in-depth, least privilege, fail securely, distrust external input, security-oriented design reviews) that reach some but not most instances of CWE-358, which is a narrow implementation error against a standardized check (e.g. protocol-level auth bypass, cert validation flaw) that can still arise in code even when the principles are followed.
