CVE-2020-27258
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 SOOIL Developments Co., Ltd Diabecare RS, AnyDana-i and AnyDana-A, an information disclosure vulnerability in the communication protocol of the insulin pump and its AnyDana-i and AnyDana-A mobile applications allows unauthenticated attackers to extract the pump’s keypad lock PIN via Bluetooth Low Energy.
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 confidenceIn SOOIL Developments' Diabecare RS insulin pump and its AnyDana-i and AnyDana-A mobile applications, an information disclosure vulnerability in the BLE communication protocol allows unauthenticated attackers to extract the pump's keypad lock PIN via Bluetooth Low Energy without requiring any authentication.

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 installed AnyDana mobile app versionOn the mobile device, go to Settings > Apps > AnyDana-A or AnyDana-I, then check the App version or Package version informationAffected if The displayed version is less than 3.0 (for example, 2.x.x)
-
Identify the Dana Diabecare RS pump firmware versionAccess the pump's system information menu (typically found under Settings > Device Info or similar) or check the firmware version displayed in the connected AnyDana mobile app's device status screenAffected if The displayed firmware version is less than 3.0 (for example, 2.x.x or any version shown without a major version 3)
-
Verify if Bluetooth Low Energy is enabled on the pumpCheck the pump's Bluetooth settings menu - look for BLE, Bluetooth, or Wireless settings and confirm whether BLE communication is turned ONAffected if BLE is currently enabled and active on the insulin pump
-
Confirm whether keypad lock PIN protection is configuredAccess the pump's security or lock settings menu to check if a keypad lock PIN has been setAffected if A keypad lock PIN is configured (the vulnerability allows this PIN to be extracted via BLE without authentication)
You are affected if your AnyDana mobile app version is below 3.0 OR your Dana Diabecare RS firmware is below 3.0, AND BLE is enabled on the pump, regardless of whether a PIN is set.
Generated from the published advisory. Verify against your own configuration.
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 data3.0
Apply vendor-supplied firmware patches when available and implement compensating controls such as restricting BLE device pairing to trusted devices only and enforcing physical access restrictions around the insulin pump.
