CVE-2017-2867
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 exploitable code execution vulnerability exists in the SavePatientMontage functionality of Natus Xltek NeuroWorks 8. A specially crafted network packet can cause a stack buffer overflow resulting in code execution. An attacker can a malicious packet to trigger this vulnerability.
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 confidenceA stack buffer overflow vulnerability in the SavePatientMontage function of Natus Xltek NeuroWorks 8 allows remote attackers to execute arbitrary code via specially crafted network packets. The overflow occurs due to insufficient bounds checking when processing packet data, enabling an attacker to overwrite stack memory and control execution flow.

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.
-
Identify if Natus Xltek NeuroWorks 8 is installedCheck system for presence of NeuroWorks software: look in Program Files for 'Natus' or 'Xltek' folders, check Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for NeuroWorks entry, or query installed programs via 'wmic product get name,version'Affected if Software is not found or version is not 8.0
-
Verify exact NeuroWorks version numberLocate the NeuroWorks executable or DLL files and check their version properties. Common locations include C:\Program Files\Natus\ or C:\Program Files\Xltek\. Right-click the main executable and select Properties > Details to view FileVersionAffected if Version is anything other than exactly 8.0 (e.g., 8.1, 8.0.1, or other)
-
Confirm the vulnerable network service is runningCheck running services for NeuroWorks-related entries using 'sc query' or 'services.msc'. Look for services named 'NeuroWorks', 'Xltek', or related to the data acquisition functionalityAffected if No NeuroWorks service is currently running (reduced exposure)
-
Assess network accessibility of the NeuroWorks serviceUse 'netstat -an' to list listening ports, or run 'nmap -sV <target>' against the system to identify open ports associated with NeuroWorks (typically port 5000-5001 for NeuroWorks network communication). Verify if these ports are bound to 0.0.0.0 or external interfaces rather than localhost onlyAffected if The NeuroWorks network service is listening on accessible network interfaces (non-localhost binding)
You are affected if Natus Xltek NeuroWorks version 8.0 is installed and the network service is running and accessible on the network.

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 dataApply vendor-supplied patches for NeuroWorks 8 immediately. If no patch is available, implement network segmentation to restrict access to the vulnerable service and consider compensating controls such as firewall rules limiting traffic to authorized medical network segments.
