5.9 mediumCVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:NCVE-2017-1000209
Medium (5.9) in nv-websocket-client project nv-websocket-client. EPSS 0.7% chance of exploitation in the next 30 days. Fixed in com.neovisionaries:nv-websocket-client 2.1.
The Java WebSocket client nv-websocket-client does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL/TLS servers via an arbitrary valid certificate.
