1. EXECUTIVE SUMMARY
o CVSS v3 7.3
o ATTENTION: Low skill level to exploit/public exploits are known for this
vulnerability
o Vendor: Insulet
o Equipment: Omnipod Insulin Management System
o Vulnerability: Improper Access Control
2. RISK EVALUATION
Successful exploitation of this vulnerability may allow an attacker to gain
access to the affected products to intercept, modify, or interfere with the
wireless RF (radio frequency) communications to or from the product. This may
allow attackers to read sensitive data, change pump settings, or control
insulin delivery.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of the Omnipod Insulin Management System are affected:
o Product ID/Reorder number: 19191 and 40160
o UDI/Model/NDC number: ZXP425 (10-Pack) and ZXR425 (10-Pack Canada)
3.2 VULNERABILITY OVERVIEW
3.2.1 IMPROPER ACCESS CONTROL CWE-284
The affected insulin pump is designed to communicate using a wireless RF with
an Insulet manufactured Personal Diabetes Manager device. This wireless RF
communication protocol does not properly implement authentication or
authorization. An attacker with access to one of the affected insulin pump
models may be able to modify and/or intercept data. This vulnerability could
also allow attackers to change pump settings and control insulin delivery.
CVE-2020-10597 has been assigned to this vulnerability. A CVSS v3 base score of
7.3 has been assigned; the CVSS vector string is ( AV:L/AC:L/PR:N/UI:N/S:U/C:L/
