Insecure SSL/TLS Server Verification in Java WebSocket Client

CVE-2017-1000209 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:N/A:N

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.
