CVE-2019-14719
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 · uneditedVerifone MX900 series Pinpad Payment Terminals with OS 30251000 allow multiple arbitrary command injections, as demonstrated by the file manager.
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 confidenceThe Verifone MX900 series Pinpad payment terminals running OS 30251000 contain multiple command injection vulnerabilities in the file manager functionality. An attacker with access to the device's interface can execute arbitrary system commands, potentially compromising the payment terminal and any connected payment infrastructure.

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 Verifone MX900 device in environmentLocate and catalog all Verifone payment terminals, confirming model numbers are MX900 series Pinpad devicesAffected if Device model is Verifone MX900 series Pinpad terminal
-
Check firmware versionAccess the device's system information or diagnostic interface and retrieve the installed firmware version numberAffected if Firmware version equals exactly 30251000
-
Verify file manager functionalityCheck if the file manager feature is enabled and accessible on the device through its configuration or admin interfaceAffected if File manager functionality is enabled or accessible on the device
-
Assess device interface exposureDetermine whether the device interface is reachable from network segments beyond the isolated payment terminal networkAffected if Device interface is accessible from network segments not dedicated to payment terminals
Your environment is affected if you have Verifone MX900 terminals running firmware version 30251000 with the file manager feature accessible.

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 dataIsolate payment terminals on restricted network segments and apply vendor-provided firmware updates when available. Until patches are released, implement compensating controls such as network segmentation and monitoring for unauthorized access attempts.
