Summary

CVE-2023-6339 is a critical-severity Missing Encryption of Sensitive Data (CWE-311) vulnerability in Google Nest Wifi Pro Firmware. Its CVSS base score is 10.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and SC-28 (Protection of Information at Rest) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

SC-13 mandates use of specific cryptography, structurally preventing unencrypted sensitive data.

SC-28 Protection of Information at Rest good match

SC-28 requires cryptographic protection of information at rest, eliminating the storage half of the weakness.

SC-8 Transmission Confidentiality and Integrity good match

SC-8 requires protecting confidentiality of transmitted information, directly stopping missing encryption on the wire.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 mostly match
prevents

PR.DS-01 directly mandates encryption for data-at-rest and therefore prevents CWE-311 mostly for storage, yet the weakness also spans transmission and other contexts that this single at-rest control leaves unaddressed.

PR.DS-02 partial match
prevents

PR.DS-02 directly eliminates the transmission facet of CWE-311 via mandatory encryption but leaves the storage facet untouched, so each direction rates only partial.

A.5.14 Information transfer partial match
prevents

Explicit rules requiring encryption for sensitive information in transit eliminate the weakness of sending data without cryptographic protection.

A.8.26 Application security requirements partial match
prevents

Explicitly calling for protection of data in transit and at rest, plus secure encryption of communications, drives the implementation of encryption that prevents clear-text exposure of sensitive information.
