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.DS-01 partial match
blocks

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

PR.PS-06 partial match
blocks

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.5.16 Identity management partial match
removes
A.5.17 Authentication information partial match
blocks

A.5.17's password management system requirements (h: store/transmit in protected form; approved crypto per 8.24; no recoverable formats implied by strong practices) stop exploitation of recoverable storage for most cases, but the remainder (non-password auth info or systems outside the password management system) is nameable.

A.8.19 Installation of software on operational systems partial match
removes
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
blocks

A.8.25 requires that security be designed and implemented in the SDLC (including secure coding, requirements, testing and training), but does not itself stop a recoverable-format password from being written into the product or stop that stored password from being exploited afterwards

A.8.26 Application security requirements partial match
removes

A.8.26 only requires that recoverable-format storage be identified as a risk and specified as a requirement; it does not itself mandate, design or implement non-recoverable storage, so the flaw (passwords stored in recoverable form) can still exist after the control is satisfied.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-922, a class-level weakness. Rules are authored against its narrower children: CWE-312.
