Likely Mitigating Controls AI

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.

CM-12 Information Location
addresses: CWE-922

Tracking information locations and access supports secure storage practices instead of insecure ones.

CP-6 Alternate Storage Site
addresses: CWE-922

Establishing an alternate site with equivalent protections directly mitigates insecure storage of sensitive backup information.

CP-9 System Backup
addresses: CWE-922

Requiring protection of backup information directly addresses insecure storage of sensitive data in backups.

PM-17 Protecting Controlled Unclassified Information on External Systems
addresses: CWE-922

Policy explicitly addresses insecure storage of CUI on external systems, requiring compliant handling and protections.

RA-2 Security Categorization
addresses: CWE-922

Proper categorization drives selection of storage controls that keep sensitive information from being stored insecurely.

SC-28 Protection of Information at Rest
addresses: CWE-922

The control explicitly requires secure storage mechanisms for sensitive information, closing the insecure-storage weakness class.

SI-23 Information Fragmentation
addresses: CWE-922

Storing information as fragments on distinct components is an architectural control that avoids insecure single-location storage of the complete sensitive data set.

SR-7 Supply Chain Operations Security
addresses: CWE-922

OPSEC requirements improve handling and storage practices for sensitive supply-chain information.

PR.AA-05 mostly match
prevents

Enforces least-privilege permissions and authorization reviews that limit read/write access to stored sensitive data.

PR.DS-01 mostly match
prevents

Protecting data-at-rest with cryptographic hashes directly prevents recoverable password storage.

PR.PS-06 partial match
prevents

Secure SDLC practices include requirements for non-recoverable password storage.

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.5.17 Authentication information full match
degrades

Directly requires secure handling and protection of authentication information, preventing storage in recoverable formats.

A.8.5 Secure authentication full match
degrades

Mandates secure authentication mechanisms that preclude recoverable password storage.

A.8.24 Use of cryptography partial match
degrades

Requires proper use of cryptography, which can mitigate recoverable storage if applied correctly to passwords.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC includes requirements that reduce the likelihood of introducing recoverable password storage.

A.8.28 Secure coding partial match
prevents

Secure coding practices can prevent developers from implementing recoverable password storage.

A.7.10 Storage media none match
mitigates

Secure reuse and disposal procedures, including cryptographic wiping and physical destruction, stop the insecure storage of sensitive data on media that may later be accessed by unauthorized actors.
