CVE-2020-27276
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 · uneditedSOOIL Developments Co Ltd DiabecareRS,AnyDana-i & AnyDana-A, the communication protocol of the insulin pump and its AnyDana-i & AnyDana-A mobile apps doesn't use adequate measures to authenticate the communicating entities before exchanging keys, which allows unauthenticated, physically proximate attackers to eavesdrop the authentication sequence 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 · moderate confidenceThe AnyDana-i and AnyDana-A insulin pumps communicate with their companion mobile apps via Bluetooth Low Energy without properly authenticating the communicating entities before key exchange. This allows physically proximate attackers to intercept and eavesdrop the BLE authentication sequence, potentially gaining access to sensitive insulin delivery communications.

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 model name on the device casing or packaging. Confirm it is one of: Sooil Anydana A, Sooil Anydana I, or Sooil Diabecare Rs.Affected if The device is any of these three models.
-
Check the installed firmware versionAccess the device menu settings to find the firmware version, or check the companion mobile app under device information. Compare the version number to 3.0.Affected if Firmware version is below 3.0.
-
Verify BLE connectivity is enabledCheck the device settings or Bluetooth status to confirm Bluetooth Low Energy pairing is active between the pump and the companion mobile app.Affected if BLE communication with the mobile app is enabled and active.
-
Confirm BLE pairing methodReview the BLE pairing process during device-app setup. Note whether the device performs mutual authentication before establishing the connection.Affected if The device does not require proper mutual authentication during BLE pairing.
A user is affected if they use an AnyDana A, AnyDana I, or Diabecare Rs insulin pump with firmware below version 3.0 and have BLE pairing enabled with the companion mobile app.

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 proper mutual authentication during BLE pairing, using secure key exchange mechanisms with entity verification before allowing communication between the pump and mobile application.
