CVE-2019-10967
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 · uneditedIn Emerson Ovation OCR400 Controller 3.3.1 and earlier, a stack-based buffer overflow vulnerability in the embedded third-party FTP server involves improper handling of a long file name from the LIST command to the FTP service, which may cause the service to overwrite buffers, leading to remote code execution and escalation of privileges.
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-based buffer overflow vulnerability exists in the embedded third-party FTP server component of Emerson Ovation OCR400 Controller version 3.3.1 and earlier. The vulnerability is triggered when the FTP LIST command processes an excessively long file name, causing the service to overwrite stack memory buffers. This allows remote attackers to achieve arbitrary code execution with elevated privileges.

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 the Emerson Ovation OCR400 Controller modelLocate the controller model number on the physical hardware label or check the system inventory/documentation for Emerson Ovation OCR400 devicesAffected if The device is not an Emerson Ovation OCR400 Controller (different models are not affected by this specific CVE)
-
Determine the firmware versionAccess the controller's web interface, console, or management software and locate the firmware version information (typically found in System Info, About, or Status sections)Affected if Firmware version is 3.3.1 or earlier - these versions contain the vulnerable FTP server component
-
Verify if FTP service is enabledCheck the controller's configuration settings, services list, or network exposure settings to determine if the FTP server is currently enabledAffected if FTP server is enabled and accessible - this is the attack surface required to trigger the buffer overflow via the LIST command
-
Assess network exposure of FTP portUse network scanning tools (such as nmap) or review firewall rules to determine if TCP port 21 (FTP) is exposed to network segments outside the trusted control system networkAffected if FTP port 21 is accessible from untrusted or external network segments - this indicates higher exposure risk for remote exploitation
The environment is affected if it runs Emerson Ovation OCR400 Controller with firmware version 3.3.1 or earlier AND has the FTP server enabled and accessible to potential attackers.

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 firmware patches when available; until then, isolate the affected controller from untrusted networks and disable or restrict FTP access to minimize attack surface.
