Medtronic 2090 Carelink Programmer Vulnerabilities (Update C)
The affected product uses a per-product username and password that is stored in a recoverable format.CVE-2018-5446 has been assigned to this vulnerability. A CVSS v3 base score of 4.9 has been calculated; the CVSS vector string is (AV:P/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N). The affected product 's software deployment network contains a directory traversal vulnerability that could allow an attacker to read files on the system.CVE-2018-5448 has been assigned to this vulnerability. A CVSS v3 base score of 4.8 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N). The affected product uses a virtual private network connection to securely download updates. 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).
