Legal Notice
All information products included in https://us-cert.cisa.gov/ics are provided "as is" for informational purposes only. The Department of Homeland Security (DHS) does not provide any warranties of any kind regarding any information contained within. DHS does not endorse any commercial product or service, referenced in this product or otherwise. Further dissemination of this product is governed by the Traffic Light Protocol (TLP) marking in the header. For more information about TLP, see https://us-cert.cisa.gov/tlp/.
Risk evaluation
Successful exploitation of these vulnerabilities may allow an attacker with physical access to a 2090 Programmer to obtain per-product credentials to the software deployment network. These credentials grant access to the software deployment network, but access is limited to read-only versions of device software applications.
Critical infrastructure sectors
Healthcare and Public Health
Countries/areas deployed
Worldwide
Company headquarters location
Ireland
Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage onus-cert.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.gov in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
Recommended Practices
These vulnerabilities are not exploitable remotely.

The product does not verify it is still connected to this virtual private network before downloading updates. The affected products initially establish an encapsulated IP-based VPN connection to a Medtronic-hosted update network. Once the VPN is established, it makes a request to a HTTP (non-TLS) server across the VPN for updates, which responds and provides any available updates. The programmer-side (client) service responsible for this HTTP request does not check to ensure it is still connected to the VPN before making the HTTP request. Thus, an attacker could cause the VPN connection to terminate (through various methods and attack points) and intercept the HTTP request, responding with malicious updates via a man-in-the-middle attack. The affected products do not verify the origin or integrity of these updates, as it insufficiently relied on the security of the VPN. An attacker with remote network access to the programmer could influence these communications.CVE-2018-10596 has been assigned to this vulnerability. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is. (AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H).",
