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 · unedited
A deserialization of untrusted data vulnerability exists in NI VeriStand Waveform Streaming Server that may result in remote code execution. Successful exploitation requires an attacker to send a specially crafted message. These vulnerabilities affect NI VeriStand 2024 Q2 and prior versions.

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 confidence

A deserialization of untrusted data vulnerability in NI VeriStand Waveform Streaming Server allows remote attackers to execute arbitrary code by sending specially crafted malicious serialized messages that are processed without proper validation during deserialization, leading to complete system compromise.

MitigationApply vendor-supplied patches to upgrade beyond NI VeriStand 2024 Q2; as an interim control, restrict network access to the Waveform Streaming Server port using firewall rules or network segmentation to prevent unauthorized attackers from sending malicious payloads.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify NI VeriStand installation
    Check system for NI VeriStand installation by looking for the software in installed programs (Windows Control Panel > Programs and Features) or checking common installation directories such as C:\Program Files\National Instruments\VeriStand
    Affected if NI VeriStand is found installed on the system
  2. Determine installed VeriStand version
    Open NI VeriStand or check the version through NI MAX (Measurement & Automation Explorer), or right-click on the VeriStand executable and view Properties > Details to find the version number
    Affected if The installed version is 2024 or any version lower than 2024 (e.g., 2023, 2022, earlier releases)
  3. Check if Waveform Streaming Server is enabled
    Open the VeriStand Workspace or System Explorer, navigate to the Targets section, and inspect the Waveform Streaming Server configuration to see if it is enabled
    Affected if Waveform Streaming Server is enabled and running on the target system
  4. Assess network exposure of Waveform Streaming Server
    Identify the port used by Waveform Streaming Server (typically configurable in VeriStand configuration) and check if it is listening on network interfaces accessible from untrusted networks using netstat or by reviewing firewall rules
    Affected if The Waveform Streaming Server port is open and accessible from network segments that contain untrusted or external systems

The system is affected if NI VeriStand version 2024 or earlier is installed with the Waveform Streaming Server enabled and exposed to network attackers who can send malicious serialized messages.

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.

dbcve · scoped
Upgrade available Upgrade to a release after 2024
Interim mitigation

Apply vendor-supplied patches to upgrade beyond NI VeriStand 2024 Q2; as an interim control, restrict network access to the Waveform Streaming Server port using firewall rules or network segmentation to prevent unauthorized attackers from sending malicious payloads.

Recommended fix Moderate confidence

NI VeriStand 2024 Q3 or later

  1. 1. Identify the current NI VeriStand version by opening NI MAX and checking the Software section, or by checking the installed programs list.
  2. 2. Navigate to the NI VeriStand downloads page at www.ni.com to obtain the latest version.
  3. 3. Download NI VeriStand 2024 Q3 or later (versions after 2024 Q2 contain the fix for this vulnerability).
  4. 4. Before upgrading, back up any custom VeriStand project configurations, workspace files, and system definition files.
  5. 5. Uninstall the current version of NI VeriStand via Windows Add/Remove Programs.
  6. 6. Install the downloaded newer version of NI VeriStand.
  7. 7. After installation, restore project configurations from the backup.
  8. 8. Verify the Waveform Streaming Server is functioning correctly by redeploying a test waveform and confirming data streams properly.
Caveat NI VeriStand version upgrades may require corresponding updates to NI LabVIEW, MATLAB, or custom software that integrates with VeriStand; verify compatibility of dependent software before upgrading
