For it to work you must disable Adobe Reader's sandbox or you can replace it with other shellcode.\nYou can see it in action (with the sandbox disabled) [here](https://www.youtube.com/watch?v=DlgtEqGRzwU)\n\nFor more info on how it works, read our [blogpost](https://medium.com/faraday/who-needs-js-when-youve-got-turing-complete-fonts-c6a9cadbb665).\n\n\n## How to use:\n1. Generate exploit charstring: `python3 .\\generate_exploit_charstring.py --output charstring`.\n2. Embed charstring into a pdf file: `python3 .\\charstring2pdf.py --filename .\\charstring --out exploit.pdf`.\n3. Open pdf file with Adobe Reader DC.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finfobyte%2Fexploit-cve-2021-21086","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Finfobyte%2Fexploit-cve-2021-21086","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finfobyte%2Fexploit-cve-2021-21086/lists"}
