A specially crafted value of the Sec-Websocket-Protocol header could be used
to significantly slow down a ws server.
for (const length of [1000, 2000, 4000, 8000, 16000, 32000]) {
const value = 'b' + ' '.repeat(length) + 'x';
const start = process.hrtime.bigint();
value.trim().split(/ *, */);
const end = process.hrtime.bigint();
console.log('length = %d, time = %f ns', length, end - start);
}
The vulnerability was responsibly disclosed along with a fix in private by
Robert McLaughlin from University of California, Santa Barbara.
In vulnerable versions of ws, the issue can be mitigated by reducing the maximum
allowed length of the request headers using the --max-http-header-size=size
and/or the maxHeaderSize options.
7.4.5
Bug fixes
UTF-8 validation is now done even if utf-8-validate is not installed
(23ba6b29).
Fixed an edge case where websocket.close() and websocket.terminate() did
not close the connection (67e25ff5).
7.4.4
Bug fixes
Fixed a bug that could cause the process to crash when using the
permessage-deflate extension (92774377).
7.4.3
Bug fixes
The deflate/inflate stream is now reset instead of reinitialized when context
takeover is disabled (#1840).
The debug dependency has been reverted to ~3.1.0, as the newer versions contains ES6 syntax which breaks in IE
browsers.
Please note that this only applied to users that bundle the Socket.IO client in their application, with webpack for
example, as the "official" bundles (in the dist/ folder) were already transpiled with babel.
// in that case, details is an error object
console.log(details.message); "xhr post error"
console.log(details.description); // 413 (the HTTP status of the response)
// details.context refers to the XMLHttpRequest object
console.log(details.context.status); // 413
console.log(details.context.responseText); // ""
});
