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.

SC-23 Session Authenticity
addresses: CWE-319 CWE-614

Eliminates cleartext exposure of session identifiers or tokens that would allow hijacking.

SC-8 Transmission Confidentiality and Integrity
addresses: CWE-319 CWE-614

The control explicitly requires confidentiality protection for transmitted information, preventing cleartext exposure of sensitive data.

AT-3 Role-based Training
addresses: CWE-319

Role-based training covers secure transmission methods, mitigating cleartext transmission of sensitive data.

CA-3 Information Exchange
addresses: CWE-319

By requiring documented security controls for information exchanges, the control reduces the risk of cleartext transmission of sensitive data.

CM-13 Data Action Mapping
addresses: CWE-319

Mapping transmission actions in data flows helps prevent cleartext transmission of sensitive information.

CM-6 Configuration Settings
addresses: CWE-319

Settings can enforce secure transmission protocols to prevent cleartext transmission of sensitive data.

MP-1 Policy and Procedures
addresses: CWE-319

Policy addresses secure transport and handling of media to avoid cleartext transmission of sensitive information.

PM-17 Protecting Controlled Unclassified Information on External Systems
addresses: CWE-319

Enforces safeguards against cleartext transmission of CUI when data leaves organizational boundaries to external systems.
