CVE-2023-4570
Ni Measurementlink 1.0.0 – 1.1.1
Raw vector
CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-4570 is a high-severity Unprotected Alternate Channel (CWE-420) vulnerability in Ni Measurementlink. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Fallback Channels (T1008); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

Vulnerability Data
An improper access restriction in NI MeasurementLink Python services could allow an attacker on an adjacent network to reach services exposed on localhost. These services were previously thought to be unreachable outside of the node. This affects measurement plug-ins written…

Mitigating Controls
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.
Usage restrictions and authorization for remote access protect against unprotected alternate channels.
TSCM surveys detect and neutralize unprotected alternate channels introduced by surveillance equipment or modifications.
Removes or disables unprotected alternate I/O channels that could otherwise be used to bypass primary controls.
Mitigating Controls (NIST CSF 2.0) AI
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.
Network monitoring can surface use of unprotected alternate channels but does not prevent the design flaw.
Protecting all data-in-transit directly mitigates unequal channel protection though the control addresses broader transit scenarios.
Network protection from unauthorized access inherently requires securing every channel, not just primaries.
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.
Network security controls ensure all channels receive equivalent protection, directly addressing unprotected alternate channels.
A.8.21 ensures that network services have identified and enforced security features (authentication, encryption, access rules, monitoring) on allowed channels; it does not address or stop exploitation of an unprotected alternate channel that the product itself leaves exposed.
Network segregation can reduce exposure of alternate channels but does not guarantee equivalent protection levels.
A.8.3's core (access restriction per policies, config mechanisms, identity/group controls, isolation, dynamic techniques with auth/encryption/time-bound rules) stops exploitation of unprotected alternate channels in the dominant case of differing logical protections; the bounded remainder is physical alternate channels (explicitly scoped to PE family in analogous 800-53 anchors) plus fully external channels outside any managed system/app/service.
