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-2 Literacy Training and Awareness
addresses: CWE-522

Training instructs users on protecting credentials from disclosure or unauthorized access.

AT-4 Training Records
addresses: CWE-522

Training records for security awareness and role-based training verify education on credential protection practices, tangibly reducing risks from mishandling or exposing credentials.

IA-5 Authenticator Management
addresses: CWE-522

Protecting authenticator content from unauthorized disclosure and modification while requiring protective controls addresses insufficiently protected credentials.

IA-6 Authentication Feedback
addresses: CWE-549

Obscuring feedback includes masking password input (e.g., asterisks), which addresses the weakness of missing password field masking.

PL-4 Rules of Behavior
addresses: CWE-522

Rules of behavior include credential protection and non-sharing requirements, reducing exposure of insufficiently protected credentials.

PS-4 Personnel Termination
addresses: CWE-522

Terminating or revoking credentials stops use of insufficiently protected or lingering credentials post-termination.

SC-28 Protection of Information at Rest
addresses: CWE-522

Requiring confidentiality/integrity protection for stored credentials directly mitigates insufficiently protected credentials on disk or in configuration stores.

SC-37 Out-of-band Channels
addresses: CWE-522

Credentials or keys delivered out-of-band are not exposed to interception or inadequate protection on the main transport.

PR.DS-01 full match
prevents

Encrypting data-at-rest fully prevents insecure credential storage while only partially satisfying the broader data-protection outcome.

PR.DS-02 full match
prevents

Encrypting data-in-transit fully prevents interception of credentials in motion while only partially satisfying the broader data-protection outcome.

PR.AA-01 mostly match
prevents

Credential management practices directly reduce insecure storage/transmission but do not guarantee encryption or transport protection.

PR.AA-04 mostly match
prevents

Protecting identity assertions covers conveyance of credentials but is narrower than full credential lifecycle protection.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper UI controls such as password masking to prevent observation.

PR.AA-03 partial match
prevents

Authentication policies cover password handling but the subcategory focuses on credential strength and MFA rather than entry-time masking.

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.5.17 Authentication information mostly match
prevents

Requiring protected storage, transmission, and non-display of passwords prevents credentials from being stored or sent in clear text where they can be harvested by unauthorized actors.

A.8.11 Data masking mostly match
prevents

Data masking directly addresses hiding sensitive values such as passwords on user interfaces.

A.8.24 Use of cryptography mostly match
prevents

Protecting secret and private keys against disclosure and unauthorized use decreases the exposure of credentials that are stored or transmitted in recoverable form.

A.8.5 Secure authentication mostly match
prevents

Forbidding clear-text transmission and display of passwords, plus the use of stronger alternatives to passwords, prevents credentials from being obtained or reused by attackers.

A.5.10 Acceptable use of information and other associated assets partial match
prevents

Acceptable-use expectations that cover protection of credentials and information assets throughout their lifecycle discourage practices that expose or mishandle authentication material.

A.6.2 Terms and conditions of employment partial match
prevents

Contractual clauses that survive termination help ensure that credentials and other secrets are not retained or misused after employment ends.
