CVE-2020-27269
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, the communication protocol of the insulin pump and its AnyDana-i and AnyDana-A mobile applications lacks replay protection measures, which allows unauthenticated, physically proximate attackers to replay communication sequences 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 confidenceThe insulin pump (Diabecare RS) and its companion mobile applications (AnyDana-i, AnyDana-A) use a Bluetooth Low Energy communication protocol that lacks replay protection. An attacker within BLE range can capture and replay legitimate communication sequences to potentially inject unauthorized commands, including insulin delivery commands, without 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 insulin pump modelLocate the device label or packaging to confirm whether the pump is a Sooil Anydana A, Sooil Anydana I, or Sooil Diabecare RS modelAffected if The device is any of these three models and the firmware version is below 3.0
-
Determine the installed firmware version on the pumpAccess the pump settings menu or pump status screen to view the firmware version number; alternatively, check the companion mobile app device information section if pairedAffected if The displayed firmware version is less than 3.0 (for example, 2.x, 1.x)
-
Check mobile app versionsOpen the AnyDana-i or AnyDana-A mobile application and navigate to the app info or settings to view the installed application versionAffected if The mobile app version corresponds to firmware below 3.0 and the app is still paired with an affected pump
-
Verify BLE pairing statusCheck whether the pump is currently paired with a mobile device via Bluetooth; review BLE connection logs if available on the mobile appAffected if The pump is actively paired over BLE while running firmware below version 3.0, exposing the replay-vulnerable communication channel
The environment is affected if the insulin pump firmware or the paired mobile app firmware is below version 3.0 on any of the Sooil Anydana A, Anydana I, or Diabecare RS models.

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
Implement replay protection mechanisms such as sequence counters, timestamps, or challenge-response authentication in the BLE protocol layer. Add cryptographic session tokens with expiration and implement mutual authentication between the pump and mobile application.
