Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn out-of-date version of Redis shipped with NI SystemLink Server is susceptible to multiple vulnerabilities, including CVE-2022-24834. This affects NI SystemLink Server 2024 Q1 and prior versions. It also affects NI FlexLogger 2023 Q2 and prior versions which installed this shared service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceNI SystemLink Server and NI FlexLogger ship with an outdated version of Redis that is vulnerable to CVE-2022-24834 and potentially other Redis vulnerabilities. This is a supply chain vulnerability where the bundled third-party component contains known security flaws.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if NI FlexLogger is installedOpen Windows Control Panel > Programs and Features, or check the installation directory (typically C:\Program Files\National Instruments\FlexLogger) for the presence of FlexLogger. Note the installed version from the program listing.Affected if FlexLogger version is 2023 or earlier (2023, 2022, 2021, etc.)
-
Check if NI SystemLink Server is installedOpen Windows Control Panel > Programs and Features, or check the installation directory (typically C:\Program Files\National Instruments\SystemLink Server) for the presence of SystemLink Server. Note the installed version from the program listing.Affected if SystemLink Server version is 2024 or earlier (2024, 2023, 2022, etc.)
-
Identify the bundled Redis componentLook for a Redis installation within the NI product directories. Common paths include C:\Program Files\National Instruments\FlexLogger\redis or C:\Program Files\National Instruments\SystemLink Server\redis. Check for redis-server.exe or redis-cli.exe files.Affected if Redis executable files exist within the NI product installation folders, indicating the product bundles Redis.
-
Determine if the bundled Redis service is runningOpen Windows Services (services.msc) and look for a Redis service, or run 'sc query redis' or 'Get-Service redis' in PowerShell to check service status.Affected if A Redis service associated with NI products is currently running, making the vulnerability potentially exploitable.
You are affected if you have NI FlexLogger 2023 or earlier, or NI SystemLink Server 2024 or earlier, and the bundled Redis component is present and running.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate NI SystemLink Server to a version newer than 2024 Q1 and NI FlexLogger to a version newer than 2023 Q2, or apply any available NI patches that update the bundled Redis component to a patched version.
