CVE-2018-14786
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 · uneditedBecton, Dickinson and Company (BD) Alaris Plus medical syringe pumps (models Alaris GS, Alaris GH, Alaris CC, and Alaris TIVA) versions 2.3.6 and prior are affected by an improper authentication vulnerability where the software does not perform authentication for functionality that requires a provable user identity, where it may allow a remote attacker to gain unauthorized access to various Alaris Syringe pumps and impact the intended operation of the pump when it is connected to a terminal server via the serial port.
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 · moderate confidenceBD Alaris Plus syringe pumps (models GS, GH, CC, TIVA v2.3.6 and prior) have an improper authentication vulnerability where the software does not perform authentication for functionality requiring user identity. When connected to a terminal server via serial port, a remote attacker can gain unauthorized access and impact pump operation.

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 your BD Alaris pump modelLocate the model label on the device or check the device inventory documentation to confirm the pump is one of the following models: GS, GH, CC, or TIVA.Affected if The pump model is GS, GH, CC, or TIVA and the firmware version is at or below 2.3.6.
-
Check the installed firmware versionAccess the pump's settings or maintenance interface to view the firmware version. This is typically found in the system information menu or on the device's display during startup. Compare your version to the affected range: firmware version 2.3.6 or prior.Affected if The displayed firmware version is 2.3.6 or any version lower (for example, 2.3.5, 2.3.0, etc.).
-
Determine if the pump is connected to a terminal server via serial portInspect the physical connections and network configuration of the pump. Check if a serial cable connects the pump to a terminal server or network-connected serial device. Review network diagrams or physically examine the setup.Affected if The pump is physically connected to a terminal server or remote access device via its serial port, exposing it to network-based access.
-
Assess network accessibility of the terminal serverReview firewall rules, network segmentation, and access control lists to determine whether the terminal server connected to the pump is reachable from untrusted network segments or the internet.Affected if The terminal server is accessible from untrusted network segments, DMZs, or external networks without proper access restrictions.
Your environment is affected if you have a BD Alaris GS, GH, CC, or TIVA pump with firmware version 2.3.6 or lower that is connected to a terminal server accessible from untrusted networks.

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 pump networks from untrusted segments, restrict physical and network access to terminal servers, and apply vendor-provided patches or firmware updates when available.
