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.

AU-13 Monitoring for Information Disclosure
addresses: CWE-209

Detects error messages that leak sensitive information as evidence of disclosure.

IA-6 Authentication Feedback
addresses: CWE-209

The control directly mitigates generation of error messages containing sensitive authentication details by requiring obscured feedback instead of verbose responses.

SC-30 Concealment and Misdirection
addresses: CWE-209

Misdirection allows generation of misleading error messages that withhold or falsify sensitive details.

SI-11 Error Handling
addresses: CWE-209

Explicitly requires error messages to avoid including sensitive or exploitable details while still supporting corrective action.

SI-15 Information Output Filtering
addresses: CWE-209

Validation ensures error messages contain only expected, non-sensitive content and blocks leakage via verbose errors.

SI-17 Fail-safe Procedures
addresses: CWE-209

Fail-safe procedures can be defined to suppress or sanitize error output, reducing generation of messages that contain sensitive information.
