CVE-2017-12724
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 · uneditedA Use of Hard-coded Credentials issue was discovered in Smiths Medical Medfusion 4000 Wireless Syringe Infusion Pump, Version 1.1, 1.5, and 1.6. The FTP server on the pump contains hardcoded credentials, which are not fully initialized. The FTP server is only accessible if the pump is configured to allow FTP connections.
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 Medfusion 4000 Wireless Syringe Infusion Pump (versions 1.1, 1.5, 1.6) contains an FTP server with hardcoded credentials that are not fully initialized. If the pump is configured to allow FTP connections, an attacker with network access could use these predictable credentials to authenticate to the FTP server.

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.
-
Confirm device modelIdentify the physical device or network asset as Smiths Medical Medfusion 4000 Wireless Syringe Infusion Pump. Check device labeling, inventory records, or network scanning results for this specific model name.Affected if The device is not a Medfusion 4000 pump - different models are not affected by this CVE.
-
Check firmware versionAccess the pump's administration interface or check system information screens on the device itself. Look for a version indicator labeled as firmware version, software version, or system version.Affected if The installed version is 1.1, 1.5, or 1.6 exactly. Versions outside this range (such as 1.2, 1.3, 1.4, or later) are not listed as affected in this CVE.
-
Verify FTP server statusAccess the pump's configuration or settings menu. Look for an option related to FTP server, remote access, or network services. Determine whether FTP connectivity is enabled or allowed.Affected if FTP server functionality is turned on or configured to accept connections. If FTP is disabled entirely, the hardcoded credentials cannot be exploited even on affected versions.
-
Test FTP service accessibilityFrom a system on the same network, attempt to connect to the pump on TCP port 21 using an FTP client. Check if the pump accepts FTP connections or responds to FTP requests.Affected if The FTP service is reachable and accepts connection attempts. An unreachable or non-responsive FTP service reduces exploitability.
You are affected if your Medfusion 4000 pump runs version 1.1, 1.5, or 1.6 AND has the FTP server enabled to accept network connections.

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 dataDisable the FTP server functionality on the pump if not required for clinical operations. If FTP access is necessary, contact Smiths Medical for a firmware update that addresses the hardcoded credential vulnerability.
