CVE-2017-1000209: Improper Certificate Validation

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...

Name of the Vulnerable Software and Affected Versions nv-websocket-client affected versions not specified Description The issue concerns a failure to verify the server hostname against the domain name in the subject's Common Name CN or subjectAltName field of the X.509 certificate. This allows...

undertow: IO thread DoS via unclean Websocket closing

It was found that with non-clean TCP close, Websocket server gets into infinite loop on every IO thread, effectively causing DoS...

Denial Of Service (DoS)

ws is vulnerable to denial of service DoS attacks. A malicious user can pass a GET request to the application with a Sec-WebSocket-Extensions header that uses the Object.prototype property name to crash the application...

Denial of Service

Overview Affected versions of ws can crash when a specially crafted Sec-WebSocket-Extensions header containing Object.prototype property names as extension or parameter names is sent. Proof of concept const WebSocket = require'ws'; const net = require'net'; const wss = new WebSocket.Server port:...
