CVE-2019-19752
nvOC through 3.2 ships with SSH host keys baked into the installation image, which allows man-in-the-middle attacks and makes identification of all public IPv4 nodes trivial with Shodan.io.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
