GHSA-3f48-9j7q-q2gv NI MeasurementLink Python Services Improper Access Restriction vulnerability

• PyPI ni-measurementlink-service: < 1.1.1 → fixed in 1.1.1 • PyPI ni-measurementlink-service: >= 1.2.0.dev0, < 1.2.0 → fixed in 1.2.0

Impact 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 in Python using version 1.1.0 of the `ni-measurementlink-service` Python package and all previous versions. Patches Upgrade all Python measurement plug-ins to use `ni-measurementlink-service` version 1.1.1 or later. References Visit ni.com/info and enter the info code `cve-2023-4570` for more information.
