PDF.js Vulnerability Demo Project

This project is intended to serve as a proof of concept to demonstrate exploiting the vulnerability in the PDF.js (pdfjs-dist) library reported in CVE-2024-4367

Getting Things Running

• Fork and clone from this repository
• npm install
• npm run dev

Testing Things Out

• First go to http://localhost:4321/

• Choose whichever frontend framework component you want to test out (react, vue, svelte) by clicking on its corresponding card

• Make sure the sample PDF (not exploiting the vulnerability) loads up

• You can find and analyze all the sample PDFs in the /public directory. Each one attempts to demonstrate different ways to exploit the vulnerability.

• When ready to test out a PDF that does exploit the vulnerability change the PDF file that the component is pointing to with the one you want to try

  For Example:

  // src/components/ReactPdfViewer.jsx
  <Document
    file='/ex1.pdf'
    onLoadSuccess={onDocumentLoadSuccess}
    options={{}}>
