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.

AT-3 Role-based Training
addresses: CWE-312

Training on secure data handling discourages cleartext storage of sensitive information.

CM-13 Data Action Mapping
addresses: CWE-312

Data action mapping can detect storage actions that leave sensitive information in cleartext.

CM-6 Configuration Settings
addresses: CWE-312

Configuration policies can mandate secure storage methods to avoid cleartext storage of sensitive information.

MP-1 Policy and Procedures
addresses: CWE-312

Policy requires protection measures such as encryption for sensitive data stored on media, preventing cleartext exposure.

SC-12 Cryptographic Key Establishment and Management
addresses: CWE-312

Key-management policy requires protected storage of key material, preventing cleartext storage of sensitive cryptographic keys.

SC-28 Protection of Information at Rest
addresses: CWE-312

Requiring confidentiality protection for information at rest eliminates cleartext storage of sensitive data on persistent media.

SC-38 Operations Security
addresses: CWE-312

Reduces cleartext storage of sensitive data when OPSEC identifies and mandates protection of key information artifacts.

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

PR.DS-10 mostly match
prevents

Explicitly calls for removing confidential data from process memory, directly mitigating cleartext storage.

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 cleartext secrets in memory dumps or debug output.

A.7.14 Secure disposal or re-use of equipment partial match
mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

A.7.9 Security of assets off-premises partial match
mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

A.8.10 Information deletion partial match
degrades

Secure deletion practices reduce residual cleartext after use, but do not prevent initial storage.

A.8.11 Data masking partial match
mitigates

Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.

A.8.12 Data leakage prevention partial match
mitigates

DLP tooling can monitor and block processes that leave sensitive data unencrypted in memory.
